Thank you @rsavoye, your rapid response saved a lot.

Dear Mueschel, I am back to tell you that issues have been cleaned and everything is ok now,
thanks for the guideline you provided, it serves as a learning material for me.
At the end, I learnt so much.

Hi @mueschel, I hope you are ok.
thanks, waiting for me for the feedback on the data I uploaded on OpenStreetMap database with wrong tags or not following proper protocols from FMTM project.
after making proper consultation on with Ralph and Ivan, Ralph guided me on what to do to make it right, as I informed you earlier that I will not prefer reverting, but I would prefer to clean it up myself,
I am requesting that you should give me 2 days maximum to fix it and I will get back to you after that to inform you on the status.
thanks, and have a great time.

Alright, thanks for this

Thank you, let me quickly look at this document/link you sent, I will quickly engage with Ralph and Ivan Gayton
Within 24 hours I should be able to give you solid feedback on reverting or cleaning out the unwanted tags.
Please be patience with this, I will surely get back to you.

Thank you Mueschel, Thank you for calling my attention
I would love to discuss this further with you
This actually the first import of FMTM data to OpenStreetMap database, it pose many challenges and I would love to engage you so we could talk more about it as I am currently working on the documentation and protocols.
Your input can help me in getting it right and we are currently working on making it better

sorry It was a mistake, I thought I undo before uploading, mistakenly made the deletion but I undo not knowing it did not work.

Thanks for calling my attention to this

Thank for you for the mapping, there are some improvements you can make on the buildings outline, make sure they match the shape of the building.
