Since the in-game bug report functionality does not appear to work at the moment, I am instead posting the bug report here. Please let me know in case there's any alternative location I can use to report issues like this and I'll be happy to report this there again.
When the capturing status of the objective switches, for example from secured to stalemate, the description text (that is, the text next to the progress circle reading "Secured", "Stalemate", "Losing",...) is not always updated correctly. The progress circle, however, is always updating correctly.
It was easily possible to reproduce this on Tell Checkpoint Security while on local play, but so far, I haven't checked this on any other maps or modes yet.
