Option "Disable compression of PSD and PSB files" works weird

App version 24.1.0
OS: Windows 10 (With latest graphic and OS updates)

I have old edited photo (few months ago) with file size 1.3gb. Recently (in the past day), I've been updated some adjustments and save and file size still the same.

Then I save absolute same file into new file, but with another name and I find difference in file size 1.2gb (in real case ~30mb difference)!

Then I decided to check EXIF and funded smth weird: old file has no compression, but new files have RLE compression. BUT in the setting nothing changed! I checked a few times.

If I disable the option to disable compression, RLE still remains. And if I enable option to disable compression, compression RLE still remains, but file actually size increase.

This operation (compression) take some time in saving file. How can I control it?

I attached EXIF info about photos and some screenshot.

Screenshot from Ps just in case.
