WKD: how to remove expired key verification

[gnupgpacker]

Hello,

a key contains an old, expired verification.

If searching this key by WKD, it shows:

$ gpg --locate-key xy at xyxy.de
pub   rsa2048 2013-10-21 [SCEA] [verfallen: 2019-03-26]
      6EB139DA63B4D15xyxyB970F435Fxy3FB0Dxyxy
uid        [ verfallen ] Pre Name <xy at xyxy.de>

Valid keys included are not shown.

How to fix this, how to deactivate/ remove expired verification?

Kleopatra screenshot attached too => Key 7217... must be removed.

Thanks for help, best regards!
