So you link something that mentions about the latest build, but you’re still using an outdated minimap mod in your screenshots, and not the default map which is shown on that link. Before you try again, disable your minimap resource, and I have a good idea that they will work.
To add, the minimap resource, was it created and exported the .dds created with it, if the minimap .gfx files do not contain the symbol for the blip and even if it has the symbol, if its missing from the blip list in the actionscript, it will not use it. Trust me, I’ve decompiled a lot of scaleforms to understand this, even created my own while researching them, Scaleform Tutorial written by @manups4e. The minimap mod/resource needs to be updated to contain the correct updates for the new blips to be used.
