You listed the item with a reserve (and have relisted it with a reserve).
There is a non-refundable charge of 4% so, if the reserve is £260, you would be charged £10.40.
You have to pay that even if the item doesn't sell or the sale falls through. As you have now relisted the item, you will be charged again, even if you cancel.
It is better to just list at the lowest price you will accept.
When you create a listing, you can add a reserve, it does say it is optional - fees apply and then, when you look at the information box, it says:
'This is the lowest price you're willing to sell an item for. A non-refundable listing fee, charged when the listing goes live, applies whether or not the item sells.'
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
