Issue with Jenkins and Git submodules

I am trying to get Jenkins working on a Windows PC and have found a weird issue with submodules.

I have a git repo with three submodules. After a while it seems I got Git itself working on Jenkins so a normal clone works. However the clone does not clone the submodules inside the main repo, so I checked the box to recursively update submodules.

enter image description here

However, when I run my job:

What does Git mean when it says:

Needed a single revision Unable to find current revision in submodule path 'top'

I have looked around and found nothing :(

I have replicated this sequence of command on a normal shell and no error appeared.

Any help will be appreciated. Thanks!

top branch sha mismatched to the commited sha for the submodule.

Consider enabling "Update tracking submodules to tip of branch" option.

This may not work for tags though.
