schedular flow conditions not executing properly

Hi

I have created a schedular flow which will execute everyday, I have added the condition that when last stage change date is older than 14 send a email

Please find following results of the flow, 

Outcome conditions

{!VarStatusAge} (14) Equals 14

All conditions must be true (AND)

Skipped this outcome because its conditions weren't met:

Where {!VarStatusAge} is TODAY() - {!$Record.App_Stage_Change_Date__c} which return the data type number with decimal 0

but when i change condition to equal 13 it is working

Outcome conditions

{!VarStatusAge} (14) Equals 13

All conditions must be true (AND)

Can you please someone explain how this logic works.

Thank you
