Error uninstalling a package: Criterion matches more than one package

David Roodman posted yesterday a discussion of xtabond2, contributed by him
I installed the package from the link he posted with the replace option
I then uninstalled it (or thought I did), and re-installed it from SSC
However, I probably did something wrong, and now when I type: adoupdate, I get:

Code:

  [113] xtabond2 at https://raw.github.com/droodman/xtabond2/v3.7.1:
        installed package is up to date

  [114] xtabond2 at http://fmwww.bc.edu/repec/bocode/x:
        installed package is up to date

I cannot uninstall either one because I get the error message:

Code:

criterion matches more than one package
r(111);
