Is there a limit to number of CART Markers you can save in a session?

Radio guy here, and when producing a group of IDs (or Jingles depending on where you're from), I will space them all out along the timeline, put Range Markers around them, and Make a mixdown to separate each ID into a separate file. This works great, but my company recently changed Automation playout systems, and it requires using CART CHUNK markers to set different timers.

My IDs all require a SEG marker to fire the next element, and I've just discovered that Audition will only save the first 8 or 9 in the session. When I close the session, and re-open it, and SEG markers above the eighth or ninth are gone and I need to reset them. The markers stay there as long as the session is open, and will transfer into the mixdown fine (for export to individual files, which keeps them as well) but as soon as I save & close the session, they're gone.

I'm trying to find out if this happens to anyone else? Is this a limitation to CART CHUNK markers? If so, why 8 are allowed instead of one? Why also do they transfer out to the mix of the session? This is leading me to believe it could be a bug in Audition.

I'm running Audition 25.3.0.71 on Win 11 Pro on an Intel i5 12500T if it matters.

Thanks
