3.3.5 Branch clones Master

so each time I try to clone the 3.3.5 Branch of Trinity core, it always clones the master. and according to your code it should get the selected branch.

:git_clone_branch
%mainfolder%\Tools\Git\bin\git.exe clone %repo% --single-branch -b %branch% %mainfolder%/Source/%sourcepath%
goto git_clone_finish

any ideas?
