When you import:

{capo: 2}
[D] [E]

What precisely do you want to achieve? Capos are used by string instruments, and in the string world this means: put a capo on 2nd position and play the chord shapes 'D' and 'E'. These will sound as 'E' and 'F♯' respectively.

So if you are a string player and want to use a capo, the best settings are to display the capo with the song (Settings > Text File Settings > Capo Display Settings), and not click the eye. If you're not using the capo, do not display the capo with the song and click the eye. 

Also, make sure that Settings > Text File Settings > Modulate Capo Down is checked.
