Ebay balance

I just sold an item and today got mail saying I had funds of £8.18.

The item was sold £18.29, With the buyer protection fee and postage label taken off, I should have funds of £14.06? I'm confused. Can someone explain

Did you owe ebay for anything?   Check here:

Hi, No.  My sale is complete. I've not sold anything for a long time. I don't know if another item I just sold the  payment is pending as it's currently being delivered.  I just can see anything what this payment of funds is as it should be 14.06.

Did you click on the link provided?

Yes, But don't know what I'm looking for. Only deductions for postage and protection

I have figured it out now, Ebay has deducted the postage price of £5.88, Off My most recent sale. I thought that would have came off after I had received payment. I don't sell a lot so bit confusing.
