Tank Combat minimod question

[xdzero]

There must be several people who play the Tank Combat SP minimod by fastlegs,

if there are may i ask what do i need to do exactly to complete the first mission (1-plains).

I basically killed every enemy tanks and infantry on the map but i only get a tick on the clear enemy on right flank objective.

destroyed schltuz's tiger but nothing happens

the the relieve dog company is a passive objective anyway, most ppl don't seem to have the same trouble i made, did i miss anything out, if you play this SP mod, please, i could really use some help.

trivia: respect to fastlegs for the awesome scrapheap challenge
