Of course you can toggle this off in preferences dialog and the checkboxes allow you to enable it only if you want to see them.
But if enabled, the plugin tries to query all the field and table IDs and show them in a new column. We use a checkbox to enable it as the query to get table/field information from FileMaker can take a few seconds on big databases.
If you like to test, email me for a copy. macOS only.
