Fixed Few Major Bugs

• Fixed an issue when a client successfully paid an invoice, an additional lowercase currency was added alongside the original currency.
• Fixed the problem where the system treated the price as 1/100th of the original price when a client tried to add a deposit.

Thanks for the fix! It should really use some test here. I missed the default items since most of the business goes thru invoice 😅
