@Jtm: Welcome back! 
I'm going to assume that you started Master of Magic in DOSBox and that you loaded a save game into it.
That you started the Tweaker independently and clicked "Connect".
Is that right?
Under the heading Wizard / <your wizard> there are 2 subtrees related to the spells in your spell book.
Apparently you have changed the "Spells known", but these are not directly the spells that you can currently research.
There is another subtree called "Research Spell candidates".
If you change that one, you'll immediately see the changes in your game (when you reopen your spell book).
The "Select initial spells" option is as yet an experimental feature, basically built on request of Catwalk.
It works, but I don't think you'll want to use it.
I should have added "(exp)" to it to indicate it's experimental.
Thanks for noting that it is white on a white background.
I don't have that myself on my screen, so there appears to be a compatibility problem. I'll fix it.
