Client doesn´t see playernames

Hey,

I updated my project from 4.18 to 4.19 and I have a problem:
I take the playerarray from gamestate and take all playernames.
This worked perfectly on 4.18 and my server still see all names in 4.19.
Only my clients can´t see the playernames from gamestate. Also the client can´t see his own playername in the playercontroller.

Does somebody knows this problem or maybe how to fix it?

best regards
