Incorrect Firefly credit usage for Upscale feature

Hello,

I noticed that the Firefly Upscaler feature on my account is deducting 10 generative credits per upscale instead of 5.

The interface clearly shows “Uses 5 credits” before running the upscale, but after processing a single image, 10 credits are deducted from my balance.

I tested this multiple times with the same result.

My Adobe account details:

Could you please check whether this is a billing issue or explain why the actual deduction is different from the displayed cost?

Thank you.
