Survivor Request XP Reward Rollback

As the implimentation of survivor request taking place now, I noticed that there's an XP rollback issue similar to what happened in earlier patches. Complete a request -> Claim the XP reward -> Everyone gets XP -> Bring some survivors to a mission (preferably on low level areas so it doesn't exceed the XP reward from the request). After completing the mission, the survivors that returned got their XPs rolled back as if the XP reward wasn't even there (if done on low level areas, you'll notice that their XP values reduced instead of increasing after the mission). I know this might be a minor issue that doesn't affect much for most players, but I still think it should be fixed since it's not how it was intended to work from the start (XP values should always be retained after gaining more, not reduced after a mission).

by low level areas, I mean those that are 10 levels below your current level because they don't give much xp as result.
