Well, your setup is clearly not vanilla anymore:
^^^ B.I.G. CA-VI-TIES !
Your framework output should look more like this:
| framework | 17.0.21 | Enabled | GPLv2+ | Sangoma |
on column 
“Unknown” != “Sangoma” 
Great!
Is anyone able to reproduce this issue on fully updated stock FreePBX from either the official Sangoma shell installer or BETA ISO, without any custom modules or third-party add-ons ?
BONUS, if you can: Once updated, please try on v17 with manual install of framework module version 17.0.21.2 via:
sudo -u asterisk fwconsole ma downloadinstall framework --tag=17.0.21.2
