Not sure how helpful this may be but… this is one thing to explore: the “Switch filter to Automcomplete at X items” property.
It could be that the first user … the one in the first screenshot would have access to more filter item choices.
So… maybe that could be something to test.
One method to test could be to build an aggregate model on the data source / object that is used in the table component shown. Then put that model in a table component of it’s own on a page on it’s own. Then render that test page with the two separate userids. If you get more results with one or the other, it may help add some info to the troubleshooting process.
