Ran DH pregen with INTERNAL_SERVER but bluemap won't see it, did I do it right?

I set dh config generation.mode INTERNAL_SERVER

And I ran I pregen of 256 chunks (attached log of re-running to check it finished)

Then I installed BlueMap

But its only seeing the chunks I generated as a player on the server

Did I do something wrong? Is more needed to pre-gen chunks than INTERNAL_SERVER?
Solution
I apparently need to re-generate with chunky then re-pregen with DH
