Unable to find amd64 package on Debian 13 Trixie

I set up the Maxscale Debian repository using the mariadb_repo_setup script, that generated this .list file :

# MariaDB MaxScale

deb [arch=arm64, amd64] https://dlm.mariadb.com/repo/maxscale/latest/apt trixie main

Then, I searched for maxscale in the repos :

maxscale/unknown 24.02.8~trixie-1 arm64

  MaxScale built using CMake

As you can see, the package is not for amd64 system.

If I replace trixie by bullseye, and remove "arm64" from the list file, I can find the amd64 package :

# MariaDB MaxScale

deb [arch=amd64] https://dlm.mariadb.com/repo/maxscale/latest/apt bookworm main

# apt search maxscale

maxscale/unknown 24.02.8~bookworm-1 amd64

  MaxScale built using CMake

If I juste remove arm64, and keep "trixie" no package is found.
