EG Riga defaults to the town or county.

Best place to be sure this is seen is to send in a request to have a new place name added or a place name improved here: https://www.familysearch.org/research/places/?pagenum=1&pagesize=20 Clicking "Suggest A New Place Name" will open a form for you to do this.
Or join the group FamilySearch Places at: https://community.familysearch.org/en/group/68-familysearch-places and place full details of what needs to be added or improved, including any alternate names that need to be added so the correct place comes up in the drop down menu.
By the way, you are just adding your own direct ancestors, right? I don't know the current FamilySearch policy, being just a regular user here, but there have been so many non-approved personal research projects by non-decendants that have added large numbers of holocaust victims to previous versions of Family Tree that FamiySearch has then removed out of respect for their families that you may find that the program flags names you are adding as confidential and keeps them in your Private space where no one else will ever see them or that they are just removed the next time the tree is surveyed for such names.
I am totally aware that LDS temple ordinances should not be done for Holocaust Victims / Jewish families.
BUT I know no such rule about adding such people to FamilySearch in general - as far as I know - peopel can do that to their hearts content.
anyone else no anything on this subject?
I have added numerous ID cards of various European Jews - many of which ended up in the death camps.
