Map Screen goes to wrong mode in activities...

I have touch disabled in Activities, when pressing up or down through data screens, often (but not EVERY time), when I get to the map screen, it has the + and - buttons (as though I'd long pressed up and then selected pan/zoom, or as if touch is activated), I click up or down to go to the next screen and it zooms the map in or out.

The only way to get out of this mode is to press back/lap - but at least once I've done this and as well as going back to normal map display (no + or - buttons), a lap has been registered, which was a pain as I was in a Workout and the button press ended the Workout and I had no idea how long I had left :/

It only happens the FIRST time I display map in an activity, all following times I can press up or down to go to the next screen as expected.

Am I missing a setting or is this a bug?
