I noticed a typo in the new JA-37Di “Akktu Stakki” Livery by Magnus Almgren.
Atleast for me it showed number "00" instead of "02" on the wings because it uses Left wing for both. If anyone have the same problem simply open up the discription.lua inside DCS World\CoreMods\aircraft\AJS37\Liveries\AJS37\37402 and change the line: {"LNS_VIG_EXT_WING_R", 0 ,"LNS_VIG_WING_L",false}; to {"LNS_VIG_EXT_WING_R", 0 ,"LNS_VIG_WING_R",false};
and that will do it :)
