Highlighted card title

[Maravilla Motta]

I was editing a title text in one card, it was to add "March 2022" to many cards, suddenly all the cards that I had already changed became highlighted in yellow, just March 2022 and the one I was working on highlighted in orange.  I don't know how I did it or how to reverse it

Hi @Maravilla Motta -- Welcome to the Atlassian Community!

Would you please post an image of what you are seeing and describe where you are seeing this in Jira (e.g. backlog, single-issue view, issue list, etc.)?

Also...

• Are you using a Company-managed or a Team-Managed project?
• Are you using a Scrum or a Kanban board?

Kind regards,
Bill
