It looks like you have a transparent background which allows you to see through the content to the panel underneath. You can either add a background or just change the panel-display
attribute to push
or overlay
instead of the default reveal
<div data-role="panel" data-display="push" id="menue" data-theme="a">
Here is a DEMO
In the demo, you can remove the data-display="push"
from the panel to see your issue reproduced.

UPDATE: the ui-panel-wrapper is definitely transparent.
Add this CSS, and the problem goes away:
.ui-panel-wrapper {
background-color: rgb(35, 71, 160) !important;
}
