[edit]
Not a bug, thanks to the answers I found the missions in the log.
Still strange that there are two reputations which need missions to get the rewards of tier 5 and all others do not *shrug*
I hit Tier 5 in Dyson and Nukara reputation yesterday and I did not get the 750 marks and 5 elite marks (in case of Dyson) for finishing them. I also hit Tier 5 on several other reputations and they gave marks just fine, affected are only the two reputations. In case it matters, the character in question was a Delta recruit I haven't played in a long time.
As mentioned above, the Dyson and Nukara reputations don't automatically award you anything at reaching Tier 5.
However, they do add missions to your Log that must be completed.

D'uh. Thank you both, I actually found missions for those two reputations in my log. They were not visible due to other missions showing in the tracker. Not a bug then!
