New CT4V Blackwing Owner, Shifter Question

Hey brand new owner of a CT4V blackwing, only 150 miles in. I've driven a manuel for the last 10 years, i've noticed sometimes specifically with just first gear or second gear, it feels like I am not fully in the gear box and then if I accelerate the gear slips out. I am not sure if I am describing it correctly... This is easily fixed by being more forceful with gear changes. Anyone else have this problem?
