Save button loading

[Nermendis]

I installed this module succesfully.
But, the buttons is just loading

Does it have something to do with this module? The error seems to be with manufacturers, not the features. If you disable this module, can you still see the error in the console?

I disabled the module, and I see the error in the console. Sorry, the manufacturer error does not belong here.

I set manufacturer and the error dissapeared.
But the button is loading.

I also have the same behaviour.
Save button keep spining can't save changes in the features tab.

Edit:I remove disabled="disabled" from the l139: feature.tpl -> submitAddproduct to test. And it saves succesfully.
