I see several possibilities being hinted at here, so let me try to restate them to make sure they are clear:

Always allow some silence at the beginning of a song, so tracks can be aligned. Your first post shows a diagram that you are doing this correctly, but following text (cutting in advance, beginning is cut off) makes me wonder when you start talking about editing. It is perfectly normal working in a DAW to nudge individual tracks left or right. Some even have a keystroke that will do this. Some also have the function to snap all tracks to a point, although most of the time this is overkill.

The players, as mentioned by Gordon and Mark, may often start early and this does NOT mean the music is misaligned. In BIAB, the guitar very often strums early in a piece that has syncopation. And of course there is the drum lead-in, if you have it set for that. This was answered for you in another thread. You have to do each track alignment by ear if you want to make a change.

In general, I suggest in this and many other threads that you become more familiar with the tools and BIAB in particular by asking questions, but in those questions try to resist implying there is something wrong or a bug. Your statement that BIAB generates misaligned tracks is simply false. It is more likely just be a case of you learning the tools, or learning how to do things. I predict you will get more help if you do not start with a false premise. I do understand some of this stems from English not being your preferred language, and I respect that.
