Can you create a test case with this behavior?

[CodingOctocat]

I can remove one item at a time, however, if I select two or more to remove, an exception will be thrown.

It seems there is a problem with the package. I've tried it with just a source, and it worked fine. I'll look into it further, but for now, you could just copy the cs file from this repo instead of referencing the package.
