and category tags are still broken 
will have a lookie under the hood again today 
edit: ok, after much tinkering and testing (sorry for all the summary posts 
) I have managed to fix the category tagging issue 
for reference, I made the following instruction changes for category and tags on all 3 summaries:
To
- Categories: always use the markdown format `#CATEGORY` for denoting specific categories.
- Tags: always use the markdown format `#TAG` for denoting specific tags.
from
- Categories and tags: use the format #TAG, #CATEGORY to denote tags and categories.
Tested the summaries and the category tagging seems to be working properly now for all of them.
