Codesys 2.3 Cross-references in ST

Hello,

I have a problem that in cross-references dialog of my Codesys POU written in ST language there are missing some occurences of variables. I noticed that it is only if the variable is inside of IF..THEN statement and not in all projects!!! For example :

***************************************************************

VAR1 := VAR2 + 1;****************read

IF VAR2 > 100 THEN***************read (missing in cross-reference)

VAR2 := 0;********************write

ELSE

VAR2 := VAR2 + 1;**************read, write

END_IF;

***************************************************************

my VAR2 is in cross-reference window only as Declaration, Read, Write, Read, Write but one Read that is as a condition of IF statement is missing. Can anybody tell me why? I tried to Build or Rebuild All but nothing. It is very strange and I lost a lot of time to find one variable in quite a big project.

Thanks
