Unable to shelve changes in v2.0.4

When attempting to Repository >> Shelve Change, geting the following error:

hg shelve -y --git --force wip 
hg shelve: option --git not recognized
hg shelve [OPTION]... [FILE]...
...

Have otherwise performed the workaround given in SRCTREE-2891.

Have tried using a System Mercurial of 3.2.4 with similar result.

Current workaround is to use patches or "hg shelve" from command line but this defeats the purpose of having SoureTree.

I should add, this problem showed up when I upgraded to v2.0.4. The problem persists even after downgrading to v2.0.3.
