MacBook Pro - won't go into sleep mode.

MacBook Pro - 16" 2021 currently running Monterey 12.0.1


I have a secondary monitor attached. The MacBook won't go into sleep mode. If I step away it just stays on all night with the screens on. Why won't it go into sleep mode? If I click the apple logo and choose sleep it just pops right back on. Any thoughts or ideas?

MacBook Pro 16″, macOS 12.0
