Ok while specing a game Helower and Skel found the solution to this problem .... Both boxes were one behind the other !
So path to fix this issue (once you enabled this option in first place , which for that in menu you need to uncheck "simple settings" at bottom, than in spectating -> team information panel and check : enable economy panel and enable as spectator ) is :
Settings -> HUD panels -> Extras -> Tweak mode
(than move the economy box and you will see another behind it (if you have same issue like i did) )
