Is there an error with development length in 7th Edition of AASHTO LRFD?

I noticed when calculating the development length for rebar in tension the lengths are much higher (6' compared to 1') when using the 2015/2016 Interim Revisions to the 7th Edition of AASHTO. Has anyone else come across this? To me, this doesn't seem correct. Has there been an errata?

I get different results, but not that much different. Are you limiting the reinforcement confinement factor (lambda.rc) to 1.0?
