Omg. This again. Do yourself a favor. Get the right size Torx bit, take the screws out, remove the level, and throw it off a bridge or over a cliff or down a storm drain. Or just put a piece of tape over it. I have two of these chassis and I learned in the first hour of owning the first one that those levels are useless.
In mounting or remounting a scope, I use the compass app on my iPhone, which has a level, to level the top of the pic rail (I've compared the iPhone level side by side with a super-sensitive and accurate engineering level; they matched). With the rifle up on a bipod and rear bag, rail level, I level my scope using a plumb line and tighten the rings. On my older scopes, I have standard-size Vortex bubble levels mounted on the tubes and set to agree with the plumb line.
On that first chassis, the little gimmick level was nowhere near agreement with the scope level. So I removed it and shimmed it. After a couple of shots at the range, it wandered off again. I never looked at it again. Never looked at the second chassis' level at all. Ever. Even if the tiny dodads were accurate, using them to level the rifle would be like trying to draw a straight foot-long line with a half-inch straight edge.
