few fms issues

Hello! I have an issue when I try to hold at a pilot created waypoint. For example, if I am assigned a hold on the mzz 180 radial at 50 dme. I create a place bearing distance waypoint and then enter that newly crated waypoint on the hold page. I get a scratch pad msg that says invalid point or something similar. I have also tried it with along track and place bearing/place bearing waypoints and they also do not work. I also noticed on the perf init page the temp deviation from isa defaults to 32 f and 0c. Should default to 0f and 0c. And one last problem I have is Im unable to enter a runway ident into the fix page. Any suggestions on what I may be doing wrong? Thanks.
