Tested both Excel adapter and PowerPoint adapter in the same Grasshopper instance and they are both working correctly after the fix from this PR.

Tested Powerpoint_Toolkit using the test script provided, and the output Powerpoint is as expected. Also tested Excel pulling and pushing, and was working as expected.
