Lj stats issue, HELP

I got a very strange problem when jumping with Exolent's Jumpstats plugin..
It don't measure my jumps if i use +duck in the end!
I't only measures my jumps if i dont use duck, like a standup longjump you know ,, then i get to see all the stats how far it was etc =S

I belive it measures every jump technics if i dont use duck, except ladderjump 'cause there it measures even if i duck .

It's a problem i can't find the solution of so im asking you if you got some clues about waht it can be,

thx in advance

ask it in his thread @ alliedmodders..?
