We have few accounts in which all the Leads are not visible in the related list. I have checked the access and I am able to access the account and lead independently. The Account lookup field on lead also looks correct, referring to the same account. There is no other account with similar name.
What could be the reason behind this behavior? Few leads are visible and few are not, does this imply any filter? But I am unable to find any configuration like that. Please help.
