Total mounts counter not showing correct amount

[levaka5459]

The Total Mounts counter shows number of mounts available to character instead of "Total" number of mounts (for all chars and both factions).
Proof: Here is a posted answer of a GM from Blizzard about the counting of mounts: https://ptr.wowhead.com/achievement=10355/lord-of-the-reins#comments (its in the comments)

Confirm

There is also a difference between what the list shows and what the achievement counts. The list will count the total number of alliance and horde mounts together, but the achievement will only count what the character has available to them. That means the achievement will only count the mounts of that particular character's faction, which is different than what the mount list will show, if that makes sense. (comments, patch 7.0.3)

Before we begin, lets make clear that the number that appears in your collection tab is not the one that matters for the achievement because this number represents the total number of mounts you own on YOUR ACCOUNT (comments patch 8.1)

Hello!
Yes, this is correct, achievement and total mounts in your collection tab are two different things, on freakz they are the same. Achievement works correctly, but Total mounts number in collection tab is wrong.

Bug confirmed.
