Flight planner is a problem since day 1 unfortunately. There are bugs threads where you can vote on. SU5 added even more USR waypoints (although they exited before).
Leads to this. EDDF/25C MARUN1D SID I believe it was (A32NX, Simbrief import).
My understanding is that they hired WT to fix it and that the G1000NXI is sort of the test vehicle to gradually replace this current FP.
(BTW. Just yesterday FBW also announced to shortly introduce their new FP in the A32NX.).
