I have two entries for attorney. The included I pasted at the bottom of this text gist.

I'm getting this error for new data entries:
jekyll 3.8.6 | Error: (/home/strike6/repositories/legal/_data/attorney.yml): mapping values are not allowed in this context at line 23 column 9

I have no clue at the moment. Best way: Ask in the Jekyll forum :)
