Audacity takes only a full second to cut - to zoom in and mark precisely what i need is not possible

[asdasd123]

Hello, i am a beginner. When i started yesterday it was possible to precisely zoom in the audio file and
mark 1/4 of a second to cute or copy it - what ever. Now i have the problem, that i only can mark a hole second, i cant precisely take a part what i want, the programm only marks a hole second. There is no precisely cut anymore. Can you help me with this. I put a screenshot in and ich hope you can help me, thx!

that i only can mark a hole second,

You have enabled snap to (nearest second).

Uncheck the “einrasten” box.
