Hello. Thank you for contacting the Toolset support.
This is a known issue to us and we already have internal ticket for this but I will add your voice to our internal ticket that might get attension and we will try to raise the priority of internal ticket.
There is no ETA when the fix made available and there is no workaround or solution I have to offer for now. Maybe if you want to try to use custom JS code to change the label's "for" attribute as required.
