ATP AD Profile Quirks

We have numerous AD profiles made on the aircraft we service. Lately, we have had 2 occasions when pulling a profile up to update it, all the categories are still there, but the previous information we had inputted, dates, times, etc. is missing. What would cause that? There are 3 of use in this repair station that access this feature and we all know not to delete things like that.
