Captions run beyond the out point into the clear timeline. Very annoying.
We have completely redesigned the captioning workflow in Premiere Pro version 15.0. You will see this feature as well as many other dramatic workflow improvements. Please update to the latest version.

Updated to 14.8 (macOS) and the bug is still there, so I have to rely on Premiere Pro 2018 for my captioning outputs, very annoying

Same thing here. They export correctly. But we are unable to view them correctly in the timeline. I was hoping that this would be fixed in the July 2018 release of Version 12.1.2, but apparently not.
