Normally, when you change the category in QuickBooks Online (QBO), the sales price should remain.
Since this is unusual behavior for QBO, try refreshing the page and logging out and back in. Then, check the Products and services tab again to see if it appears.
If the issue persists, use an incognito window to starts a fresh session without any cache or cookies that could cause the problem. You could also switch to a different browser as another option.
