Sort by Level sorts Alphabetically not Numerically

When sorting a list of monsters by level, it sorts the level number Alphabetically, instead of Numerically.

If you aren’t aware of the difference, here is a list of numbers sorted Alphabetically:
0
1
10
11
12
2
20
25
3
4
5
50
51

It’s sorting the numbers as if they were words, not integers.

I can confirm the same. For example. click game rules, creatures. search dragon
click the sort by level option at the top of the column “LVL” then go to the next page.

Immediately after the teens it goes to 2 before 20.
