Petition for mom but birth certificate discrepancy

[Bkfinest]

Hi, I know every case is different but does anyone have experience with anything similar? Well i am petitioning for my mom. I was born overseas, But on my overseas birth certificate shows her name with her maternal last name, not her paternal last name. Her documents show two last name her maternal and paternal as all documents in carribean have two last name one from each parent. But my birth certificate on my mom name it has her full name minus her paternal last name. For example her name is Maria Rosa Martinez Espinal but my birth certificate shows her name as Maria Rosa Espinal. Will that be an issue for petition? Also all of my siblings birth certificate have same issue just our moms maternal last name on their birth certificate will this be an issue also if she later petitions for them after i petition for mom?
