P: Retouch circle automatically becomes smaller on images with Transform Adjustments

I'm on the Lightroom Classic V13.3.1 and whenever I use the healing brush tool on my photo (with every click), the brush size automatically keeps shrinking (e.g. I started off with brush size 8, and it goes down by 2 notches with every healing click). It's annoying the heck out of me, and I'm not sure if it's an issue for others too. 

How can I fix this issue or is it a bug? 

With the 13.3.1 update on macOS Monterey (12.7.5) , the "remove tool" marker shrinks every time the image is clicked to remove a thing. Sometimes the mask itself is shrunk automatically, sometimes the mask obeys the marker radius..

Expected behavior: the mask does not shrink in this usage scenario (as it used to).

I believe this is a new bug, not the same bug that made the circle smaller after each stroke. That is why this is not related to transform.

Had this problem for years but has become worse with most recent update (v13.3.1). Now the jump is greater each click. Very inconvenient as I use this tool everyday. Bug occurs regardless of Lens correction or Transform tools.

It happens for me on some images but I never use Lens Correction or Transform.

Since upgrading to 13.3 the healing, remove and clone brushes don't work right. Each time I use the brush, it decreases in size. I set it to 18, click once, it's at 12; click again, it's at 8; again, 5, 3, 2, 1. It also happens with the new generative AI. Hopefully, this is a bug and not a "feature," as it is not a feature I appreciate. Tried restarting Lr and the computer, but with no effect.

While using the new Ai remove brush in normal spot removal mode not generative fill with each click of the brush to remove a spot the brush gets smaller.

Just updated LrC to version 13.3, and got this annoying bug (new to me).

It occurs also on un-transformed and no-lens-corrected images.
It does not happen if make a shape by moving the mouse, only when doing a one click.

EXTREMELY frustrating, as I have a bunch of old slide scans to clean the dust off.

Same experience here, with the spot healing tool.

Using: LrC 13.3, MacOS 14.5, M2 

This is brand new to me, with v13.3. Never experienced it before the recent update.

I'm in the midst of archiving hundreds of old '90s film prints: scan, crop, basic edit, clean, sync with Cloud.

So there's a lot of spot-cleaning to be done (normally this is a tool I use only sparingly for regular photography, but it's required multiple times per image for this project) - and, as film scans (JPEG) are the source, I'm not using lens profiles or transform tools (which this bug has been associated with).

The behaviour is not consistent - on some images, the spot circle will remain the same size, on others it will decrement in size with each application.

One thing to note (may not be relevant), but I did notice that after the LrC 13.3 / Lr 9.3 update that my entire film-scan archive (800+ images) resynched with the Cloud - i.e. not just the latest batch I'd dragged over to the synched Collection within LrC, but everything was (re-)updated.

I realise this is a known issue, but my experience doesn't involve lens profiles / transform tools.
