I've set up the following card button automation on my Trello board:
'convert all the items in checklist "Q3: Key Results" into linked cards'
However, if I run the button automation more than once (when a new item is added to the checklist) it changes existing converted card titles to a URL. [Screenshots attached]


I assume this is happening because I am running the card button automation more than once.
Questions:
1. is there a way to stop this from happening?
2. is there a way to revert the cards with URLs back to their card titles?
3. is there a way for new checklist items to automatically be converted into cards?
Thanks
