Grandma/Grandpa Local Exploit Suggester Problem

Hello, I have been trying to complete Grandma and Grandpa, I can do almost everything except for escalate my privileges, whenever I use the local exploit suggester on Metasploit, it always says it is trying 4 exploits and then says exploit complete, but nothing gets returned. Whenever I watch write ups or guide it always says 28 exploits being tried and like 8 exploits return showing privilege escalation options. I’m not sure what I’m doing wrong, I’m following the guides exactly but the suggester is not returning any results. Can someone help please?
