Unable to target recipient with leap year and non leap year birthday with same delivery

Hi team, I want to make a birthday campaign that can target recipients whose birthday falls on a leap year and nonleap year, I am following the steps from this document.

https://experienceleague.adobe.com/docs/campaign-classic/using/automating-with-workflows/use-cases/deliveries/sending-a-birthday-email.html?lang=en

and using recurring delivery 

But the campaign goes in the paused state it does not reach delivery,

but if I use the separate recurring delivery for leap and the nonleap year it works.

Please help me with how I can use a single delivery for both.
