CB Conditional & Update on Ajax

I am facing an issue with the following and I am not sure if what happens is the expected behaviour.

Field2 in Tab2 has "Update on" related to Field1 in Tab1,
Tab2 is conditionally hidden/shown based on user choice in Field1 like Option1->Tab2 Shown, Option2->Tab2->Hidden
In the case where Filed1=Option2, Registration fails (Sign up doesn't work) and in console shows Tab2 validation error in grey.

So the question here is, since Tab2 is hidden, why "Update on" tries to validate?
 

Update On has no clue CB Conditional exists. They're independent features that do not talk to each other. Regardless CB Conditional should be preventing the validation.

Regarding registration not working is the button not submitting the form or are you getting redirected back with a validation error after the form submits?

Ok, have released a new CB Conditional and CB Core Fields Ajax so the plugins are aware of each other. Fields marked with Update On will skip their updating if they were conditionally hidden. If they're then later conditionally shown it will immediately trigger an update on to be sure their values are up to date. Client side caching has also been added so duplicate Update On requests will just pull from the cache instead of redoing their HTTP calls.
