Hey there @sambbaron
I just tested the in-page analysis and seems to work well, using Divi Builder.

Are you using both Yoast and SmartCrawl? This could cause conflicts.
If not, then maybe a conflict test would reveal the source of this.
Deactivate all plugins and MU-plugins apart from SmartCrawl, activate a default theme like TwentySeventeen, clear all caches and check again if the issue is still there. If not, it means that something is conflicting, so start activating the remaining plugins and theme, one by one this time, checking every time for the reported issue, until you reproduce the issue, thus finding the conflicted combination. The following flow chart image can assist you during this test: https://premium.wpmudev.org/wp-content/uploads/2015/09/Support-Process-Support-Process.gif
Prior that, please do create a recent backup in case you lose any settings during the test and have to restore to a previous working state.
If this is a live website with traffic, I’d rather advice to create a staging environment, meaning a complete and exact copy of this installation into another location/folder in the same server, using a separate database, and perform the test in there instead without worrying about live site.
Warm regards,
Dimitris
