Your post doesn't indicate a version number for BLS-2015. What version number are you using? (Current version is 27.06.03). Always helpful to do a check for software update first...if you already did that, you can disregard.
You say "all the certification steps". Did you either manually certify all bowlers individually based on how they paid through your league or another league/association, or did you opt for the setting to treat all bowlers as certified (this is the easy way out).
I do not have my computer with me where I can direct you to where these screens are, but if nothing else, these should give you something to start on until I or someone else can do so.
Also...the only national awards that will print will be 300/800/900 as those are the only ones USBC does anymore. Anything else is association or center level and has to be entered as such.
Always check, download, and install the most recent update of your software to ensure that issues may have been corrected.
