I posted about this issue previously, marked it as solved as it was said that Adobe was aware of the issue and was being worked on in a future update.
When opening a RAW file in ACR, I am able to pick a custom LUT/Profile that I have created and it is recognized.
When editing in Lightroom Classic and applying that same LUT/Profile, it disappears once I select "Edit in Photoshop."
Lightroom's built in presets (i.e. Artistic, Modern, Vintage etc.) Those work. Third Party / Custom made via photoshop Profiles do not.
