I do both of those things too, but i did'nt think either was particularly strange
Acknowledgements seems reasonable - don't want to tempt fate plus opinions of people may change if you don't pass. I did'nt have any acknowledgements in the submitted version, I put these in after I passed.
Formatting - I don't do any of this untill i'm happy with a body of text and it is complete, my way of signing it off as a done job I suppose.
I don't think i'm crazy at all
