Hawid Mounts- What's Going On?

I posted a few months back about issues with these no longer adhering to pages using the gum on them. I got the good advice to supplement with a glue stick and that has been working.

Today I started work on a remounting project for some Great Britain stamps. In the past I have always used the 24 size for definitives, it was a perfect fit. Today I noted the 24 size mounts I was using were too short. The stamp in some cases sticks out over the top and even when it doesn't, the top half of the mount stands away from the page. It just looks jarring to me. I use clear mounts.

Apparently Hawid has reduced the sizing, possibly to save money?

Thinking of ordering some Davo self adhesives to finish the job. Any one else ever notice something similar?

Maybe just a bad lot? I would try with a new package before giving up on the brand.
