Popup does't show in the page

[JafetGranados]

Please help me with this. I have already dowloaded this project and works pretty well, but when I try to use it on another solution, the first time I show the popup this is showed at the left margin of the page and only when I turn my phone to the landscape mode the popup shows rigth, and then, when I show the popup, it shows correctly. Thank you for your help and sorry for my english.
