Combined Conditions Issues on 5RC2

Noted the following issues with the combined conditions:

1. When selecting a condition from the dialog pop up to add it to the combined field, dialog pop up closes (this is ok), but the combined condition pop-up closes also, you need to reopen it again every time to add a new condition.

2. When you delete a condition from the combined field, always the last entry is removed, regardless which one you have selected.

3. When you add a combined condition, then delete some, then re-add some new, VS always remembers/adds the old ones instead of the new.

It's easy to verify the above, but if you need more clarifications, i can try to provide some pics.
