How to debug a post on WP having the incorrect comment number

What is the proper value of the “wpdc_sync_post_comments” field?

I’m still struggling with this problem.

I just went to a topic that had one post. Comment count in the WP front-end should be “1”, but it showed 0. The wpdc_sync_post_comments was “0.” I’m assuming that’s a T/F flag, and that it should be set to 1, so I changed it and saved the post. Refreshing the WP front end showed no change, so I left a new post on the Discourse topic and immediately refreshed the WP page. Comment count had correctly jumped to “2.” Immediately refreshed the page again and it had dropped down to “0” again! In the edit screen, I found that wpdc_sync_post_comments was set back to 0 and

discourse_comments_count == 0
discourse_comments_raw ===
{"id":1451,"posts_count":3,"filtered_posts_count":1,"posts":[],"participants":[ (snip)

Another post has the following:
discourse_comments_count == 3
discourse_comments_raw ===
{"id":1447,"posts_count":17,"filtered_posts_count":4,"posts":[],"participants": (snip)
