Dear @Moetezsallami,
Welcome to the Wefugees Community and thank you for reaching out to us.
First of all, you will not have a re-entry ban if you left Germany voluntarily. Only people who got deported or "obviously unfounded" rejected asylum applicants from so-called safe countries of origin receive a ban to enter Germany/the EU after they left the country.
If you left Germany during a pending asylum procedure, the case will be closed automatically (latest if you don't show up for the interviews etc.). It might be better, nevertheless, to inform the BAMF about the misunderstanding (was it a misunderstanding?) and to let them know that you left Germany already. Did you receive a file number already? Otherwise, an email to the respective BAMF office (including your data) explaining the situation might be a first step. How do you see the situation, dear @mbeon-fardeen or @mbeon-Éanna?
Unfortunately, I can not estimate to what extent the initial application is saved in the information systems in Germany/EU and if it may have an impact in upcoming Schengen visa applications. But since you returned within the valid visa period, I wouldn't be too worried about it.
I hope this helps and all the best,
Meike
