Actually, Fuelly requires the 3 fuel-ups for the vehicle to be publicly visible/searchable from the Browse Vehicle's section.
It is true that the first fuel-up is 'skipped/ignored' when tracking via Odometer, but your second being skipped through a red-flag for me.
Taking a look at your log, I found the error-

Unless you're secretly Doc Brown, I think you may have missed a digit there on the 14th.
