Oh i just noticed something, all of the speech checks issues you're having are because of the very early and very buggy TTW_SpeechChecks.esp.
A while ago I reported that plugin so broken it needed to have a full review of it before being merged into TTW, and that is why it is still an optional plugin, unfortunately the maker of the plugin hasn't been around for a long time and never fixed it.
I think someone else on the team will have to go through that plugin and fix all the bugs in it.
For now I do not recommend anyone to use that plugin.
