Withdraw from Sparkpool

Hello,

I just got CKB from Sparkpool with the TX-ID:
0xa3ab561dea63493437a433dc3c83ffbf9228cf6bf927a8e2ff6c0ba15c3203ba

A total of 40598,48047 CKB were withdrawn, but only 20,582,45708 CKB arrived on my wallet. That is kind of really ugly.

Can you help me to clarify where the problem is?

Many thanks & greetings
Florian
