It could be a technique thing or a setup thing.
It could be technique if your fingers are still building strength and you're not pressing the fret in the right spot or the right amount. Finger strength and good fingering technique is something that develops over time. It takes a while because finger strength comes mostly from tendons which takes longer to build strength than muscles.
But if it's only happening in that range of the neck on only one string, it sounds more like a setup issue than a technique thing. You can do a setup on your own, but if you're just starting out and just learning, it's best to bring it to a tech. Big chain retailers aren't know to do the best setups. Try to find an independent one in your area and have them set it up.
Here are a couple of videos of how to do proper setups with some legends in the tech world:
My 2 cents would be, when you have the extra cash to get it properly set up by a professional in your area, have the do that to get the instrument really dialed in. Once it's dialed in, you can learn doing small adjustment jobs whenever you change strings or as the transition from winter to summer and back causes the wood to shift slightly. That way you know the pro set it up right, and you're just doing minor tweaks while you learn. The difference between playing on a properly set up bass and a poorly set up one is drastic. Definitely recommend a pro setup when you have the spare cash. It shouldn't cost too-too much.
