Duplicants disregard machine priority for some actions, or not queue it at all

I have detected this issue with a couple things, and actually submitted a bug report for the Geysers some time ago (which was the first time I noticed it). This time I noticed it with a 'Triage Cot'  so I am reporting it as a more general issue. Also, I noticed Churcy's report:

However, it seems that their bug relates to a different scenario, where even manual assignment does not work. 

In my case, I am trying to set the Triage Cots so that injured dupes get some healing at some thresholds. From what I recall, in previous versions all you needed to do was set this threshold and the task would be queued. However, in the current version (and probably in some versions before that), even marking the cot as 'emergency' does not do anything, and the dupes keep 'seeing' it as a level-5 priority. Moreover, only dupes currently assigned to a Triage Cot can detect the errand, as even candidate dupes are marked as 'not assigned'. I am attaching a couple screenshots where this can be noticed. 

In summary, it seems that there is an issue with the Triage Cot assignment (or auto-assignment). 

Hope this helps and thank you for keeping this a great game!

PS: Still wishing and hoping for a PS4-PS5 version of the game
