2.6: Campaigns conditions disapear

Updated on 2.6. Now there is a problem in the campaigns: condition based on contact field value can be selected and adjusted. BUT the fields always reset, example:

Contact Field: Core Title

Operator: equals

Value: Mrs

Klick save. Reopen again and the “Mrs” falls back to “Mr”.

Ideas?

We’re seeing the exact same behavior on fresh 2.6.1 production release installs. The problem is specifically with select list fields. Values entered into text fields are stored, but values selected from a select list (operator, country, etc) always revert to the top/first value.

Here is a video showing steps to reproduce: https://www.webmshare.com/KEO81
