Update: I found that if I use the tab key to get to the alignment and other dropdowns, I am able to change my selection. Definitely a bug.Belinda commented
Having the exact same issue on InDesign CC, but with any dropdown menu in the paragraph styles. It started happening pretty suddenly. It looks like when I click to open the dropdown menu (for font style for instance), it looks like the window becomes inactive, then when I try to select from the dropdown, it appears that I'm clicking away from the selection.
