Trendline Formula Wrong - What mistake did I make?

Hi!

In the attached graph there are 6 trendlines.
The X axis represents EVENT 10 till 100
The Y axis represent the values listed in behind MAX MAN till AUTOBRAKE 1. (6 lines in total)
I added the trendlines. Linear for the MAX MAN line and Polynome grade 2 for the other lines.
The trendlines match the data quite well.
Then I clicked to show the formulas

Those formulas are wrong.

What mistake did I make?

Many thanks for your help.
