Recardo,

Welcome to the community!

Basically it happens because of a few things:

1. Clear Browser Data/Cache.
2. Disable third-party browser extensions
3. Re-login to Trello.

Also make sure you are using a supported browser.  https://help.trello.com/article/736-troubleshooting-browser-issues-with-trello
