Zooming in on Android Tablet leads to "download sectional" error

[Test Subject]

So I am on a samsung android tablet (newest) and despite donwloading all the relevant sectionals VFR etc, when I zoom in a certain amount, it says "download sectional" but when  you zoom in farther (or zoom out) it shows the VFR sectional map as normally.

That is a very very strange error, any ideas on how to fix?
