I allocate deposits to invoices, yet the deposit still shows up on my open invoice report.  The invoice balance is reduced by the amount

Welcome back to the Community, @hvanzyl.

Once the deposit is already allocated to an invoice, it should no longer show on the Open Invoices report. To isolate this, try opening the deposit by selecting it on the report.

If it was the one you've added, try signing into your QuickBooks Online (QBO) using a private browser (incognito). This will help us check if this is a browser-related (cache and cookies) issue.

Here's how:

• Press Ctrl + Shift + N (Google Chrome).
• Ctrl + Shift + P (Firefox).
• Control + Option + P (Safari).

If it's no longer showing, return to your default browser and perform a clear cache to refresh the system. However, if the issue persists, try using other supported browsers.
