Option to switch off dialogue on Group Profile

Note that this complaint is only seen on the mobile version. Specifically when mobile is held in portrait mode.
When the dialogue ‘change’ button on the Buddypress Group (below the buddypress group profile avatar) is hit, it opens up the dialogue box with the list of options to change to. But pressing any of the options does NOT change them. In addition only half the ‘Close’ button is seen as the whole yellow box that incorporates the options is too small.
The dialogue box more often than not has only the left 2/3 seen since it is skewed to the right whenever the ‘Change’ button is pressed. If I ‘pinch’ the web page to make the page ‘lose’ any magnification, then press change again, then the dialogue box centres itself when opened. Though the options buttons still don’t work.

Note these problems DO NOT happen on the desktop version.

My suggestions:
1) Have an option on the backend menu to remove the change option from the Group profile backdrop (leaving just the change options in the BP Group settings pages)
2) Remove your own CSS design for the options box on the BP Group profile backdrop and let the theme set its own box format design (hence increasing its responsive characteristics on mobile).
