I can pick blessed warrior and fighting style feat but it doesn't give me the option to choose the feat. and on character sheet Divine sense is missing and there is no Channel Divinity tracker. 

I'm getting the same issue with unable to choose the specific fighting style feat without manually adding it through the 'manage feats" option on the character sheet itself.

Also experiencing these issues.

Same here. Divine sense/sacred weapon have different writings in the app compared to the character builder 

not being able to pick a fighting style at level two also effects the ranger class.

Working around is to manually add the feat to your character sheet

i do have divine sense on my sheet listed as an option with the channel divinity tracker on the features and traits. but the description for divine sense is on the actions. it is clickable in the tracker which opens the drawer. so this may be a less widespread bug.

the inability to select a fighting style feat in the character builder is something i am experiencing along with everyone else though.
