If you see in the Status Report error section with fields marked as mismatched this is what you can try to do.
drush entup
command was removed starting from some version, so thes method is not relevant anymore.
Given Drupal Core 9.3.3, I attempted the following process which finally resolved the errors without the drush command.
Spot where from comes the field itself, could be Paragraph, Block, Node, or other Entity.
From the administrative menu, navigate to Manage Fields and edit the field, open tab Field settings and simply click "Save".
In some cases, the field contained no data, in other case I received the warning that data was present. After saving, and returning to Status Report, the errors were resolved.
It seems as though saving through the GUI syncs up the changes in the database.
