So I made some tests. These are my results so far.
1) Test Setup
- AdMob Overlap = Yes
- Show banner at bottom
Result:
It works like it should, the banner will be shown on the bottom of the layout.
2) Test Setup
- AdMob Overlap = No
- Show banner at bottom
Result:
The banner ad is shown in the center of the screen even if it's set to show on the bottom of the Layout. So I guess the layout where the ads are shown is shifted upwards.
3) Test Setup
- AdMob Overlap = Yes
- Show banner at top
Result:
It works like it should, the banner will be shown on the top of the layout.
4) Test Setup
- AdMob Overlap = No
- Show banner at top
Result:
The banner isn't visible on the layout, that's maybe is caused by the shifted ads layout.

I compiled to version, once with setting overlap to no and once with overlap to yes.

Just use the Bottons to switch between top and bottom.
The question now is what this bug is causing. I'm not sure but I guess it isn't Construct 2, but maybe the AdMob plugin. I tried the the plugin developed by cranberrygame (Phonegap, Cordova isn't working at all on my end)
