I wouldn't touch that - its probably the offset amount that the secondary needs to be at with a relatively short focal length telescope. A lot people don't realise this. In the old days with the long focal length scopes you did centre everything, but with the modern shorter focal length offset becomes important. I'd do a bit of research on it, there must be some diagrams around to show what it is and why it matters.
I've you've joined up with the Bunbury mob, trust their opinion, some of them have been in the game a long time and know what they're doing. I think what you're describing is perfectly normal, you're just not used to what is 'normal', as you say.
I do a lot of outreach and people often expect that the telescope will magnify the stars into flaming balls of gas, or at least a round disc. Er, no, they're still far away for that...
