Slip disappears in new progress period

Hi all,

I have multiple progress periods, and for some reason, the slip values in the slip column disappear on all progress periods past the 5th one. For all progress periods 1-4, I have had no issues.

I am basing the slip on a baseline.

Nothing has changed except the value, and another reschdule, all of which are part of the processes I always follow.

Anybody have any ideas?

thanks
