Why don't my POIs appear when I export an OSM map to IMG?

I exported a OSM map of my area and converted it to IMG using mkgmap. The POIs don’t seem to have downloaded with the data.
What is the cause of that? It’s worked before on other exports.

Check what is different from the other exports you have done.

  1. different sw version
  2. different input data

There is a Garmin forum, perhaps this should be moved there
