Database update to nested table removes condition on save

I think its a bug, but if I am doing a database update to a main table and 2 sub tables, and I try add a condition, it adds, I close out, and when I go back in the condition is removed.

I am trying to make it not add entries to my subtable if no options were added at all.

@Teodor, sorry to be a pain, but could you possibly try replicate this for me, it seems to be happening more often to me, and i am not sure if its just me not understanding or an actual bug.

Can you make a screenshot showing what exactly do you mean?

Sure, here is one that seems to do it.

When i hit OK, that condition just removes itself.
