Relational Field Search fails

I have 2 Custom Types defined. Custom Type 2 has a parent field – hit the button, the list of related types (Custom Type 1) pops up just fine, but trying to filter, sort or change pages results in a blank list. Clicking show all reactivates the list, but only shows the first 10 items – there are more than 70 total. Impossible to reach the rest. Started happening after the last update.
