Obvious question but have you tried pulling on the fork until it fully extends and pushing the buttons on the lowers?I put OneUp 210mm - fits perfect, I'm probably same inseam as you.
I just noticed that Fox 38 does not extend fully, even when unweighted - I can pull on lowers and extend it by about extra 10mm. Do you notice the same?, or it's just my fork...
If it doesn't work, I'd guess, that your air chambers are not equalizing properly...
You could try apply max. air pressure and cycle trough, maybe it will open the port.
