It sounds as if you do have sticky shed problems. You can bake the tapes yourself, but that is a lot of palaver for just a few tapes - you can't just stick them in a domestic oven for 30 minutes at regulo 2. People who do this professionally use custom built ovens. There is plenty of info if you google.

You could pay to have the tapes baked and digitized if they are important to you. Several forum members can do this.
