Folder Name won't accept underscore

[davidbrooksio]

Grav v1.1.10
Admin v1.2.6

When adding a modular page in Grav admin I cannot save it because the name of the folder (with an underscore) breaks the regex validation for the input. For example, if my folder is called _slider, when I try to save the page I get a message (in Chrome) of:

Please match the format requested.

Cannot replicate - where are you getting it? In the modal directly? Can you make a screenshot?

This screenshot was taken immediately after pressing "save".
