Skill issue?

Fairly new to lickpicking - started as a way to fidget during work zoom meetings. Now I have half a dozen locks on my desk....

Anyway, after a bunch of practice, I can pick my Abus 65/40 easily enough when using top of keyway tension, but can not make any progress at all when using bottom of keyway... I'm assuming this is a skill issue, but can't find any advice! Would love to get some hints/tips!
