Unanswered No extruded filament left side

Hello!

Excuse my English, I'm from the Dominican Republic and is not our native language.

I have a problem and I'm practically begging for help because the support has not helped me at all.

The printer has given me many faults with automatic leveling of the bed. I did what I could with what I have read but now I have another problem.

The printer starts printing from the right side but it reaches the center to begin printing the left in no extruded filament. In the photos you can see what I mean. I realized that everything is leveled, the head does not hit the bed so the filament should print. I do not know what to do!!!

Please, can you explain in the simplest possible way?
