[LNN] The triangle symbol ▴ or ▾ does not appear when sorting a column

[Nylilsa]

Describe the bug
The triangle symbol ▴ or ▾ does not appear when sorting a column

To Reproduce
For this to be done you need to use both tables Overall Count and Player Ranking.

1. Go to the table Player Ranking and click on the header Games LNN'd. Next to the text Games LNN'd, the symbol ▾ appears.
2. Go to the table Overall Count and click on the header Different players. Next to the text Different players, the symbol ▾ appears. Next to the text Games LNN'd, the symbol ▾ disappears.
3. Go to the table Player Ranking and click on the header Games LNN'd. Upon (continuously) clicking on the header, no symbol appears. However, the symbol is still present in the column Different players of the table Overall Count

Expected behavior
It is expected for the symbol ▴ or ▾ to appear when clicking on the header Games LNN'd, but instead nothing appears.
