Grouped layers all moving together?

On Photoshop, I use a thumbnail template, where I have multiple groups: Title, Talent, Products, Background. I've been using that template for years now, I clean up once in a while but I have a couple of recurring images I use and like to keep in my template. Recently, even when some layers are not checked, it's like Photoshop thinks they're there? So if I want to resize one of the images that's part of any group, I need to hit free transform in order to be able to resize this image using only this image's borders. Or when I have to have 2 images on the thumbnail from the same group, I can't move them separately, it moves both of them and I need to remove one from the group to move it and then put it back in. I don't mind if that's just the way Photoshop is going to be, I'll re-organize the template accordingly, but it's kind of annoying and it didn't use to be this way up until the latest (I'm on v26.9, on PC) update? So, am I missing a quick fix?
