Thunderbird Latest version is redownloading all my emails from the server every few times I start the email program

A few days ago, when I opened Thunderbird, it began downloading all folders and emails from my server provider ( bringing the folders to date) I already removed the account and the database twice to see if it was a database issue, but it keeps refreshing all my folders and emails, which is a huge amount and takes a long time to complete. Any idea how to troubleshoot or fix this? Thanks
