Troubleshooting OSPF Route Advertisement

Hi Team,

i was doing a LAB today about OSPF topology is given below

Here i have 3 routers on multi-access network so i created 3 loopback on R1 and advertised them under OSPF. so now the thing is i am able to see all loopbacks under routing table of each router but not seeing them in LSDB can you explain why,

R1

R1#show ip ospf interface 
Loopback2 is up, line protocol is up 
  Internet Address 1.1.1.1/32, Area 0 
  Process ID 1, Router ID 192.168.20.1, Network Type LOOPBACK, Cost: 1
  Loopback interface is treated as a stub Host
