I’ve applied the latest patch, please trying saving your template again?
Regarding the sort order, I logged in to the site and set this to Title / Descending and can confirm that works correctly – if you’re still experiencing issues could you please tell me exactly which settings you used?
This is because in your marker listing you have the ID column hidden in Maps -> Settings -> Marker Listing. You need to enable that in order for it to be sorted by ID when using the Advanced Listing Marker Table.
If you enable column that you’ll find that the setting works.
