dropdown menu doesn't work

[daniel]

Using Morph browser. When trying to select from a dropdown menu (image 1), the phone opens a small window with some (not all ) the options (image 2), but they cannot be selected. If I try to open again the dropdown menu many times, the browser windows is reduced into a  small white rectangular in the top left of the screen and do not respond anymore (Image 3). Some rare times a new window open opens with selectable options (a desired behavior).

Is there any known solution for this?
