Windows Server Preview Build 25997 - Erro update - Cumulative Update for Windows 11 Insider Preview

I would ignore this as the update was released to test servicing for the client builds. Its probably showing up because of the build number\branch being identical. Doesn't do any harm. Build 26010 will go live at some point then this won't be a problem. (https://blogs.windows.com/windows-insider/2023/12/07/announcing-windows-11-insider-preview-build-26010-canary-channel/)
