Mini Marathon on Synology not working?

Saw the topic here:

I'm still seeing similar behavior though. I set up a Virtual Channel with a Mini Marathon sorting. I have 6 or 7 shows in it, I've tried it with less and with more. Instead of seeing 2-episode blocks that rotate through shows, I'm seeing what appear to be indefinitely repeating blocks of the same two episodes of a single show.

The linked topic suggests this was fixed in a pre-release. I've done "Check for Prerelease" and updated. I'm running 2023.08.09.2030 on a Synology DS918+ (DSM7).

Just curious if this is a new issue, if this fix hasn't made its way to Synology, or what.

Thanks!
