Away a While - Did I Get Super Downgraded by Avid?

I bought Sibelius Student back around 2007. I kept using it through all the changes to the subscription models at Avid, and Avid has given me Sibelius First in the meantime. I use it mostly for piano transcription, so I haven't noticed any significant loss of functions.

I had a big move in the last year, and I'm opening up my Sibelius First for the first time in a while. I only have access to 2 of 4 voices, I can only do 4 staves instead of my 8 given from Sib. Student, and, most importantly/urgently, I can't make any adjustments to staff sizes or spacing. Did I get screwed by Avid in the end? Does anyone know whether I have access to these functions? Looking for any advice. Thanks.
