Currently, the font counters are misleading because they track individual font files instead of font families.
For example, I added “Funnel Display” to my favorites. Even though it is the only family I’ve added, the counter shows 7 instead of 1 because the family contains seven files.
Similarly, while there are roughly 2,000 Google Font families, the counter displays over 8,000 because it is counting every file. Users typically expect the count to reflect font families, not individual files.
