Unfortunately, Boge forms 3 'pimples' in the shock tube to hold the aluminium sleeve (Koni weld on a proper ring). These bumps effectively lock with the softer aluminium sleeve - so it becomes a question of which must be saved, and which is sacrificed: the sleeve won!

About your front height, if you have the adjuster nut there, then the threaded sleeve must be inside. It may be seized to, and spinning with the adjuster nut, thereby preventing any adjustment. If it were not there, then the spring perch would sit 20mm lower than the minimum adjustment - and be directly resting on the shock support ring.This would result in a very low ride height.
The front and rear adjusters are two different interpretations of the same principle: the rear is a narrow nut that carries the perch up and down an ~80mm tall threaded sleeve. This sleeve is located by the shock body ring. Conversely, in front a 45mm tall nut covers a ~20mm tall internal threaded sleeve. The perch load is carried by the nut until the nut is backed off to its minimum height position. At this point, the perch sits directly on the sleeve - and the nut spins freely.
Get out the wrenches ....
If not seized as noted above, you should be able to lower the front to spec.

Having said that, there is a good chance that a soak in penetrant and the proper hook wrench will turn the front adjusters.
