Hi houtari, 
thanks for bringing this issue up to conversation. I have saw that 329 road segments do not have Swedish as their primary name and 185 of them are named by our team. 

We will deep dive into this and correct the issues. However, there was a complain from the community when we asked about adding default Sweeden name in these parts of Finland, and the answer was not all of the roads have Sweedish name as a primary one. This is why we added Finland name as default in name value, however, we also added both name:sv and name:fi variants and so both data exist in correct manner. It was expected that community will react and correct name tag using local knowledge.

If you are 100% sure that name should be the same as name:sv in these cases, we will go and fix the issue. Can you claim that is the case?
