Device icons not showing on map

I am having a problem similar to this: https://www.traccar.org/forums/topic/no-icon-and-name-of-vehicle-showing-on-map/
I am using the huabao protocol on port 5015. Everything else is working perfectly (device status, alerts) for around 1500 devices, but icons are not showing on the map. Below is a sample of the browser console. I am trying to use the answer in that link but I don't know where to start

The issue is that device reported invalid coordinates. Remove device that has the problem.

Any hint how to spot the device. I have over 1400 devices just wondering if there is any easy to know the faulty one

You can try to run an SQL script to find coordinates out of range.

Could this be a protocol problem? I run a query and found more that 30% (or 400) of devices have sent invalid coordinates. I have sent you an email about with more details

OK, I have found the problem. There was some junk positions that were submitted before using osmand. Deleting these solved the problem. Thank you
