When you say, "most current", please specify. There have been a number of people whose CC app was saying AE was up to date, but it was 13.5 (and, in some cases, 13.0) neither of which are current. So I always like to double-check. Which Mac OS are you using?
MAC OS 10.10.5
That's odd. I don't have my Mac with that version handy to test right now. I'll try to remember to check tonight.
In the meantime, add a text animator with rotation set to -90 and everything should be back the way you expect it.
You don't already have a text animator applied to that layer, do you?
Yes, that's what I wound up doing; that and then adjusting the tracking. There was nothing on it before- it came straight out of the type tool that way. I've restarted AE and My computer etc. Not the biggest deal, but still really annoying.
That sounds really annoying. My Mac isn't doing that, but then, I am running El Capitan, so I can't perfectly match your system. Same version of AE though.
You might try resetting your preferences to see if that makes a difference.
