Changed Font Size - Won't Change Back

[Jon_Kreski]

I recently changed my font size to 150%.  I wish to change it back to AUTOMATIC.  When I tick that and close out of the dialogue, re-start and go back in it is still set at 150%.  What am I missing?  This is annoying because the library grid went to 3 x 2 and only half of the second row of images fit.  Help!  I am on a Windows 11 PC.  Everything is freshly updated and the computer has been freshly re-started.  Thanks.

Try resetting LR's preferences:

LR sometimes soils its preferences file, and resetting it can fix all sorts of wonky behavior. That article explains how to restore the old preferences if resetting doesn't help.
