Yep, certainly doesn't sound right and worth pursuing.
Contact eBay Customer Services if you do so now, there's a better chance of Dublin answering, only speak to them, it's a Call Back option, so you'll hear if it's the dulcet tones from the Emerald Isles. Ask for some explanation of this very strange decision.
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.
As said, I recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
