Auto complete on branch names not working after installing this

[Devenom1]

I'm not sure if this is the right place to raise this issue.

I love these shortcuts. But I can't do stuff like branch auto complete.Like if I run this command
git checkout feature\something

It auto completes.But if I run
gco feature\something

It doesn't.

Update: Sometimes it does but after a minute or so. It's really slow. Rest of the time it doesn't
