Layer lock doesn’t work

Hi there,

Not sure if this is isolated but when I create a layer with a background on I want to lock that layer so I don’t move, delete or accidently drag it. This doesn’t seem to work. See video: https://www.awesomescreenshot.com/video/38729665?key=b40be45ebaa75a990ad664d3fc024f19

It’s a cool plugin and definitely will be utilised for our social platform website. Just need to figure out how to lock layers.

Any help on this is much appreciated.
