@pohrerhub You haven’t done anything wrong,
This just means the linked objects cannot be edited.
When linking into a file with library overrides, Blender creates overrides of a lot of data blocks, to reduce the amount of information and risk of potential unwanted editing, most of those data-blocks are marked as non-editable by default.
There is a lot to learn on Library Overrides, check this on Blender.org for more info.
Ideally you would make changes in the original file.
You can make a data-block editable by right clinking the object in the outliner > ID Data > Make Library Override Editable
I hope this helps
