Why is there Fluid usage if Fluid Compute is disabled for the project?

Under the Usage tab in Vercel, a project has usage under Fluid Provisioned Memory and Fluid Active CPU, however the project does not have Fluid Compute enabled.

Why is this happening?

I have the same issue! Fluid compute disabled, but still has usage days after disabling it. Could anyone help here?

Really bad that nobody from Vercel replied, seems they don’t care…

But apparently edge functions eg. middleware run on Fluid, and as far as I understand this cannot be switched off, hence the usage.

Go to Fluid Active CPU in the Usage tab and select Type, what do you see?
