I think there is a bug in the range mask toolWhen i try to apply range mask with lightroom classic CC to a psd or tiff file (previously created in photoshop and saved back to LR to continue editing) it doesn't work at all. I mean moving the slider in the range mask do not produce any effect.
This is the work flow . start editing a raw file in lightroom 2) export to photoshop 3) editinf on PS 4) save the file in PS 5) editing back in LR and rang mask do not work
If I use range mask with a raw file it works well
