Rename Droplist item

I have droplist with some items. I have interaction for every item in the list. If I decide to rename these items, I have to map all interactions again, because renaming broke these connections (item -> interaction).
What is the reason behind this disconnection?

Thank you.

Hi Siq!

Could you tell me a little bit more about the interactions that are being used when you encounter this issue? A screenshot of your interactions, or a copy of your RP file may be useful in troubleshooting this issue. Could you also please confirm whether you are using Axure RP 8 or Axure RP 9 when this occurs?

Thank you!
