no complete map

Your tabs is not like I though.
Now I download tab extension you use, add some parameters and will do new release.
In your tabs it uses simple index to access tab (ie to know what tab is clicked). But I though they will add some ID. I played with simple tabs, in common case it have some properties to access diretly to tab, but no problem, I will do.

I did release for your case.
In Override details on Map tab you should set

Invalidate Map Size
Container Selector

Container Index
Invalidate Type
And all will be OK

Check Extension Manager for new release. Clear Cache, then Find Updates.
There is new version of component.

Sorry for my mistake. You Container Index is 0
Your map on the first tab.
