fix the logic of finalizing the prohibition of adding identical fields in the interface

Recently, you have improved the functionality for the interfaces of processes and contacts, which prohibits the repeated display of fields in various universal blocks http://prntscr.com/ue6ajl . I understand that you did this in order to stop throwing errors that “I filled in the field, but I didn’t save it”, but the logic you implemented significantly violates the already configured functionality on working projects specifically: each universal block has a display condition, i.e. show it depending on the payment method, customer type, etc. and so, the logic of the given option implemented by you does not consider , i.e. the fact that the same field can be in two or more universal blocks, BUT in the interface it is displayed ONCE anyway, because I eliminate the problem with duplication precisely through block display control logics I ask you to add an additional check for how the field is displayed in the USER interface, and not how many times it occurs in the block settings.
