Hail @APerk - there are a few issues it could be.
If it’s just on the A string, and it goes away after the 5th fret, it could be the string tension (angle of the string from the nut to the tuning peg (as @gcancella suggested).
A photo of the bass headstock / nut / first fret area would help to diagnose that.
The rest of it would have to do with the nut/bridge/truss rod.
To know what these things do and how to adjust them, there are great resources and videos on this thread:
If nothing above fixes it, it could be a fret at the 5th or below that is too high, and the fix for that would be something I’ve only had other people do on my instruments.
Holler with any further questions or more photos/details!
