Upon deleting an expression at the automember rule page, all the expressions from both Inclusive/Exclusive tables disappear. They appear back on refresh (without the deleted expressions).

Steps to reproduce:
1. Go to an automember rule detail page
2. Create some expressions in both Inclusive/Exclusive tables
3. Delete one or more expressions from either table by selecting them and clicking "Delete".

Expected result:
The table that contained the deleted expression(s) gets updated according to the changes.

Actual result:
All expressions from both tables disappear.
