Why are the Swedish records still coming up incorrect?

This question was brought up a year ago. It seemed that there was some improvement being made for awhile. However the issue is continuing. More record hints are coming up with the mother's maiden name listed as the children's surnames even though a surname is not listed on the actual record.

The records were indexed correctly and can not be edited. The naming in Sweden is already tricky and this compounds that.

We know the issue is that the mother (with her maiden name) is listed above the children so that name is being dropped down to the children even though no surnames are listed for them.

This has not always been a problem - so it seems that it is one that can be corrected.
