I forgot to mention that the radio button is inside a flexible content field, and it looks like the problem is related to this field. It works fine inside a repeater field and on its own. Everything other then “0” seems to work just fine.
The issue seems to be solved and it is working as it did before now. Not sure why it stopped working there for a while.
It is only a visual element in the form I am after, and not effecting the value in any way. Putting “+50” inside a span, so it it “<span>+50</span>” in the prepend or append field seems to solve the issue. The “+” is stripped away when I add “+50” so the result is “50″ being appended to the field.
I was able to hide a field using css and the data-field_name on the <tr> tag before, and now I am not able to do this anymore. The only way I can do that now seems to be with js and that seems like a poor solution for my current problem. I’m trying to hide fields that are not relevant based on current language on the edited post, on a multi language site. I need to do this to be able to easily synchronize the repeater field data between languages with only a bit of language specific data.
