Al-Ubaidi is classified as a neighborhood, not a suburb. The locations you referenced, such as "كفاءات العبيدي" (Kafa'at al-Ubaidi), are adjacent to Al-Ubaidi. The correct name for this particular neighborhood is simply "الكفاءات" (Kafa'at), as reflected in OpenStreetMap: https://www.openstreetmap.org/node/4727144491/history . However, locals often refer to it as "كفاءات العبيدي" (Kafa'at al-Ubaidi) to distinguish it from similarly named neighborhoods in other parts of the city (for example, when giving directions to a taxi driver or speaking to someone from another area of the city), as these are under different administrative jurisdictions.   
Kindly provide official documentation confirming any reclassification of Al-Ubaidi as a suburb. Otherwise, I will proceed with reverting the change.
