Pro-ject Turntable Tonearm Dropping Too Slow

I'm having an issue with my Pro-ject Carbon Debut Carbon Esprit turntable. Whenever I cue a record from the beginning, the tonearm lowers perfectly. But if I try lowering it further towards the center, it comes down way too slow. Sometimes it will even skip a little at that spot until the stylus makes full contact. Most of the time I play my records from start to finish, so it's not that bothersome. Any ideas of what might be causing this?
