Conditional resets on save

I recently updated from Webforms 7.x-3.24 to 7.x-4.11 and I have a problem with the conditionals using select options. When I try to save a conditonal it resets from 'select - is' to 'time - is at'.

What I am doing:
1. Create select options field A with two options: 0|yes and 1|no.
2. Create a text area field B
3. I create a conditional entry with 'IF Field A is 0' then 'Field B is shown'
4. Save
5. The entry now reads 'IF Field A is at 0'

I also tried using the value rather than the key as condition with 'is yes', but that doesn't work either.

I am not using any additional webform related modules save Options Elements for the UI. I used to use Select or Other but I disabled the module and uninstalled it before testing.
