There are a number of issues in the consecutive changesets you made here. In this changeset you tried to fix the errors that were created by the wrongly added footway.

In this and the previous edit you've converted path to footway, when there is a local preference for these Dartmoor horse & foot ways to be mapped as paths.

I reverted the two changesets in 160879128 & 160700871

I'll look at the paths that were added and add them were appropriate in a new edit.
