Invisible Tables after Updating PHP and the Plugin

We bought the previous Pro Version and updated to PHP 7.4. Then tables disappeared right after modifications. After upgrading the table plugin to the latest version even all tables disappeared online and remained within WordPress incompletely. We generally lost the content of the last row. And by going back to PHP 7.3 we were unable to reconstitute the missing content.
In the meantime the plugin was made working under PHP 7.4. Thank you. But we have to invest 2 full working days to complete all the tables again. This caused a big financial damage. I understand that incompatibilities can occur due to PHP updates, but it should be impossible that table contents get irreversibly lost and have to be rebuilt manually.
