Problem with ACCEL1 and ACCEL2

Hello!

I am having problems with accel1 and accel2 cards. When  I apply the loads they exist in the input file but when I run the analysis and look at the results, 3 of 9 accelerations are not applied. The 3 cases that are not working are all applied on the same node. Any ideas?

The marked cases are the ones where the accelerations are not applied. The two first cases are not accelerations.
