如何消除流氓“计数器"在我的Windows Store主页上?

我有一个简约的主页-4个按钮和一个必应地图.

I have a minimalistic main page - 4 buttons and a Bing Map.

但是，当我运行该应用程序时，我在左上角和右上角看到两个流氓计数器"(不知道如何描述它们).这是左上角的那个:

When I run the app, though, I see two rogue "counters" (don't know how else to describe them) in the upper left and upper right. Here's the one on the upper left:

是什么原因造成的，我该如何摆脱它们?

What's causing them, and how can I get rid of them?

顺便说一句，左边的黑色竖条是按设计的"(没有双关语)-在计数器"下面是我的四个按钮，它们是垂直堆叠的(我故意给Bing地图只提供了页面的80％，而不是贪婪地从git-go抓取的100％).

BTW, the black vertical strip on the left is "as designed" (no pun intended) - below the "counter" are my four buttons, stacked vertically (I deliberately gave the Bing Map only 80% of the page, not the 100% it greedily grabbed from the git-go).

对于Ashok:XAML就是这样:

For Ashok: Here's all there is to the XAML:
