Firdst Contact missions have been broken in this way since Season 4. Plenty of players have /bugged it, yet the issue persists, so obviously, it's either VERY VERY VERY low priority; or Cryptic has no clue how to repair the problem.
(And it's the same with the 'Borg Red Alerts where the button has just popped up in your instance - you press it immediately - yet find yourself in an EMPTY/devoid of Borg enemies instance -- and they used the same broken code base for Tholian Red Alerts as the above happens with them too - but this is also a case of something that has been brokn and /bugged by players since Season 4; yet no fix has been forthcoming.)
The Devs may not realize the bugs still exist as they probably don't attempt to play the content much themselves; and after spending time doing NUMEROUS tickets on the subject, they may not be seeing anymore bug tickets in their queue as most players (myself included) don't feel like wasting time reporting a pretty obvious issue that -- for whatever reason (good or bad); the STO Dev team has no real interest or ability to correct (IMO - because if they did, these bugs wouldn't still exist after more than a year -- OR they'd try to get some focus testing on Tribble or something to find and fix the root causes.)
