Lists intermittently showing zero data

Good evening,

I inexplicably receive this message that there are no items in a list that DOES indeed have data in it that I have been using for years (other users I ask can see data, but I cannot for whatever reason).

In the screenshots, you will see I show data in the list at 4:25PM PST, I refresh my screen 1 minute later, and zero content now. The same issue occurs after clearing Chrome cache, using Incognito, and using a different browser all together. What is happening?? 

Thank you in advance for your input, 

Morghan C.
