CRM 2015, Remove option from multiple instances of the same optionSet field on a form

Hi all,

I have a form in which I added the same field (optionset) in multiple tabs. 

I'm trying to remove an option from that optionSet field, however, after the Javascript is executed to remove the option from all the field instances, the only one affected is the one located on the first tab.

Can anyone help me to understand how this can be done using javascript using the removeOption() method?

thanks in advance,

Alexander
