It may be the same as the issue with the quarterly vintage reporting that LC does, in the downloadable files. They don't start reporting on the vintage until the period is ended, and 2017 only ended a few months ago, and 2018 hasn't ended yet.
Regarding 2yr CDs at the credit union ... I'm earning about 5% at LC these days, which is more than the local credit unions are paying. That's down a lot from what it used to be, and I wish it were higher, but it is what it is.
