[SambaPOS 2.99] Cash Up Issue How does it work?

Hi, We’re still using Samba POS V2.99 CE, How exactly does the Cash up report works? More especially with the Credit Card Tips? On our credit card speed point we enter the tips separately. and then we add it on the POS with the Tip template. Somdays we are short and some days we are over on our cash ups. like this morning we were short. but the amount short was the amount tips that was but through on our speed point. but there is no difference on our Credit Card Amounts? Can any one assist me with this issue?
