I would turn them over. I always dry fruits with a "skin" with the cavity up. It keeps the flesh contained. Yours will be fine though.
Keep going, they are awfully thick so need to make sure you have enough moisture removed. They should be leathery when done. The drier parts will rehydrate some when you put them all together in in a bag or jar.

For the next batch see the instructions in the article linked below - scroll down to Drying part. Sulfuring them first gives the best results and definitely face up.

Here is a link that might be useful: Dehydrating Apricots

I know this is a little late for this year because in most places apricots are long gone but I had a little advice to help you dry your apricots. We sold U-pick fruit for many years and I was complaining to one of our u-pickers about the same problem. She said just turn them inside out. She meant to put your thumbs in the skin side of the apricot half and push up. This breaks apart the tissue connections on the inside of the apricot and makes it dry twice as fast. You still dry them face up.

Thanks for the help. I dried the second batch skin side down and they came out much better. I don't want to use sulphur so the skin is really dark but they still taste yummy.
