Facebook Scraping Issues

Facebook scraping has recently stopped working for my new posts. The debugger says that the og:image:width and og:image:height properties need to be set when I debug the first time and no image displays (but when I view source the article they are present and accurate)

When I debug a second time, the images appear as if nothing is wrong.

What can be causing this issue?

My website is http://www.rapwave.net if you want to check out any of the individual posts’s tags for troubleshooting.

Thanks in advance.
