No jdea where you are looking, but I can only see one item sold on the 14th in your completed items.
This may be an ebay glitch, but when you sell, buyer has 4 days to pay, there is nothing automatic about money appearing in your account.
Once sold, item shows as SOLD AWAITING PAYMENT, once paid it is then in PAID AWAITING DISPATCH, when you post it then moves to PAID AND DISPATCHED.
Selling all new items and you need to be registered as a business seller, before ebay catches up with you.
More steps to address false private sellers
At eBay, we are dedicated to ensuring a fair and equitable marketplace for all business sellers. To achieve this, we monitor trading activities, and we’ll continuously help business sellers using a private account to transition to a business account, or restrict selling activity as necessary. In addition, we’ve reduced the number of free listings available to private sellers.
