Since installing wpmudev standard free-member theme (WPMU

Since installing wpmudev standard free-member theme (WPMU DEV Dashboard) - i found that the Page description in my Word Press does not allow for graphical manipulation, instead, it is fixed on an HTML view only - snapshot attached.

Can someone assist.

PS Note, i will not proceed with the theme unless i feel comfortable that the theme does not affect my maintenance operation ...
