Data Error ~ Spins retreiving data (Sorry... error retreiving data)

I have a form that has the section in a Hardware App.

Under the section Acknowledgement of Equipment Receipt, when the Tickets tab is selected (the default) the error message with a 'spinning circle' says, 'Sorry... error retreving data'.

If I chose the other tabs, data loads. I just noticed this a couple days ago. Any ideas?
