problems with "My Album" function in iPhoto
I'm using iPhoto version 3 in High Sierra 10.13.4 on a mid-2014 MacBook Pro. Problem: I can't get a «My Album» (not a smart album) to recognize a Keyword, it worked yesterday, but not today, very strange (1) I want to delete the «My Albums» I created and use Smart Albums instead but (2) I can't find any way to delete a «My Album» I created. Any Ideas?
MacBook Pro with Retina display, macOS High Sierra (10.13.4)
