Clicking on the descriptive bar while adding modules breaks groups view

[Bounz]

From https://homegenie.club/t/cant-access-group-in-homegenie-hg-hangs-when-trying/127/4.
When inserting a new module, it is inadvertently clicked on the descriptive bar that separates the different modules.
In this case, a line of code with the wrong syntax is incorrectly inserted into the groups.xml file and this breaks groups in HG.
