Ion-select behaviour changed from platform to platform

#1

I am working on IOS hybrid app, when I used ion-select than it display the proper options for selection (android build), but when I am build the app for IOS platform and tested on device the behaviour of dropdown completely changed on some devices ( ios 6 and more devices ). On IOS device options are displayed completely blank.
Thanks in advance…
