Android wrong element positioning

If i run my app in desktop browser or in ios simulator everything looks like expected, but when i run the app on my android device (4.4.4) there are problems with positioning of elements. For example in the navbar:

        <ion-nav-bar class="bar-light nav-title-slide-ios7">
            <ion-nav-buttons side="left">
                <button class="button" ui-sref="products">Home</button>
                <button class="button" ui-sref="matches">Matches</button>
                <button class="button" ui-sref="settings">Settings</button>                                

The first two buttons are displayed correct but the last one is line wrapped. If i would add a fourth button, the first three would be displayed correct and the last one gets line wrapped.
It seems like, that the problem only regards to the last element.

Someone got a solution?
