Why do I have such a big difference in my Stableford results?

Hello,
First of all, I'm quite new to golf, maybe I'm just not savvy enough to see my mistake myself.

As you can see in the picture, I have the Garmin scorecard at the top.
Below is the digital scorecard from my golf club, both show 55 strokes distributed exactly on the right holes.

But both show me completely different Stableford results.

As far as I understand it, as a player from Europe I have to use Local Handicap because Index/Stroke does not work, which I have done, my handicap is 54 and I have also entered this in the clock.

Thanks for your help, this topic has been bugging me for several rounds, never got to the result of other Stableford sites.
