Editing Text Content in Email Templates

Editing Text Content in Email Templates

Hi,

I'm experiencing issues with modifying email templates in both CRM and Campaigns. Creating a new one is fine, but once it has been saved, I am unable to make any changes to a text box content type. This is happening regardless of whether I try to modify a Header or standard Text content block.

Tested on three different computers and two different browsers (Chrome, Firefox) with the same result. 

Any help would be really appreciated.
