Ionic popover and actionsheet css not work

Hi,sorry for my poor english.
First, my development environment:
I create a dynamic web project in eclipse and copy all files that in the ionic project ‘www’ folder to ecplise project webContent path.So I can debug on pc and mobile web browser.

I have a problem.ionic popover and actionsheet css not work.
the popover use the “list list-inset” css class and the actionsheet use default css class.On PC the css works fine, but on the mobile, sometimes it works,but most of the time it dose not work.

Is there any problem with my situation? thanks!
