Thanks for letting me know! I found the issue. I guess in 2.0 the mining result dictates what actually ends up in the blueprint, and in the previous versions of the mod the mining result was plain asphalt.
Fixing this will have the side effect of the painted tiles dropping themselves when mined, which some people might prefer anyways. JSYK you will still be able to reconvert tiles back to normal asphalt by holding them on your cursor and pressing "J" by default.
I'll work on fixing this, and push out an update most-likely later today unless some unforeseen issue pops up. Apologies for any inconveniences with this issue.
