Facebook Share count not showing

Hi guys

The Facebook share count is not showing any share counts, see here:
https://dressageridertraining.com/article/glute-strengthening-exercises-for-riders/

But this page according to Facebook Debug tool has 41 shares: https://developers.facebook.com/tools/debug/?q=https%3A%2F%2Fdressageridertraining.com%2Farticle%2Fglute-strengthening-exercises-for-riders%2F

Then I have another page, see share counts showing as 66 counts: https://dressageridertraining.com/article/lower-cross-syndrome/

But Facebook debug tool says only 33 shares: https://developers.facebook.com/tools/debug/?q=https%3A%2F%2Fdressageridertraining.com%2Farticle%2Flower-cross-syndrome%2F

Do you know what could be causing this?

I followed exact steps you provided on this page here: https://www.ultimatelysocial.com/how-to-create-a-facebook-app/
But I did not do the second half of the article that requests Facebook for approval, as I only wish to show share counts of each blog post.

Thank you for any help you can provide.
