I would think eBay Customer Services will suggest to send the 2 buyers feedback revisions to complete.
Otherwise , you can contact eBay Customer Services explain the neutrals wrongly placed are affecting your sales limits, but the feedbacks do not exactly break feedback rules, so they may not remove them. Worth a try.
This is the easiest and quicket way to contact eBay Customer Services, for a Call Back option.

Lines open between 8 a.m. to 10 p.m. on weekdays.
9 a.m. to 6 p.m. on weekends.
I recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
