Explorer map generated impropelry

Used the following command:
/give PlayerName filled_map 1 6 {Decorations:id:"+",rot:180,type:8,x:127,y:127}}

UPD:

Was able to create map with line:

/give PLayerName filled_map 1 6 {Decorations:[

{id:"+",rot:180,type:8,x:127,z:127}

]}

"House" icon is shown. Map is updated correctly. However, the problem with absence of Player's position arrow still persists.

Also, "scale" tag seems to be ignored.
