De-selecting target markers

[GunnyCook]

Any chance you could fix this please?

 

Select an artillery unit/group,

Add enemy unit as its target then commence firing,

select another friendly unit (a tank for example)

now go back to the first artillery unit and try and de-select its target.

 

i cant seem to select the the target marker no matter how far i zoom in or out, it always picks up the unit being attacked.

 

Thanks
