[Bug] POIs with same labels on Bluemap will only display one of them in Xaero's Map in game

[yqs112358]

Currently I am using this mod to create waypoints from Bluemap. But I have found that POIs with same labels on Bluemap will only display one of them in Xaero's Map in game. Screenshots are as follows:

Both these three POIs are shown on Bluemap:

But only one of them is displayed in game:

The data of these POIs in Bluemap's database are:
