Express help. Layers that are locked with allow replace are now movable. Something changed recently.

I made a template for YouTube Thumbnails in our style a few weeks ago but coming into it now there has been changes/glitches. 

We have multiple differnet show logos/podcasts/stations that have logos that need to be swapped out, so I created them on a 1920x1080 canvas so they are sized properly when the user “replaces” the logo for the logo they need. 

This was working well and the user could still click on the background layer to change the photo grid either 1, 2,  or 3 photos . There are six pages in this template two different looks with three images variations. 

However this week when you go to click on the background to change the image, you can only select the logo thats sized to fit the whole screen. and also that layer is moveable when it should be locked and only allowing replacement. This was different than it was behaving when I made this a couple weeks ago and replacing the images in the grid was seemless. 

Also it would be very helpful if you could shift click on layers in the layers panel to group. or name layers . we have to train a lot of producers on how to use these templates and its really hard to preview what a layer is based on a grey thumbnail. 

Thanks
