ACCOUNT members disappear after refresh

Hi,

I have following issue with my input forms:

I create forms with set of ACCOUNT members in row axis. I tested, saved, closed - everything seemed to be fine.

After some time when I reopen form and refresh it account members disappear - all or some of them.

Sometimes my members are substituted by context member.

It does not happen always but quite often and I can not find a clue what is a reason - I am already quite tired fixing forms all the time.

Can anybody suggest whay to do to stop that?

Thanks!

Andrzej
