Data Not Loading Until Page Refreshed

When switching to my apps through my navigation bar in the header, the main table does not load any data, yielding a message of "No Rows Found".

But if the user then refreshes the page, it then all loads just fine.

I figured the query behind the main table wasn't running, so I set a page load delay of 750ms. That hasn't helped though. Any suggestions on how this can be fixed?
