Title video codec not matching footage codec

I'm in the process of learning/transitioning to Avid, and here's what I'm in the middle of trying to figure out:

I transcoded h.264 1920x1080 29.97 files to DNxHD 220 X (HD1080p). I've edited a sequence with them, and added a title using the title tool. I saved the title and looking at the Video information in the bin, it says the codec is DNxHD 145 (HD1080p). Why is that, and how do I fix this so the titles I create are the same codec? Also, I noticed my timeline does not list a Video type - why is that, and how do I know what I'm editing in?

Understanding Avid's codecs is something I'm trying to grasp, so any information is appreciated.

Thank you kindly.
