Whatsapp / iCloud / Dual Sim / Backup issues?

iOS 16.2

SIM and e-SIM in use, 2 different numbers

1 Whatsapp (e-SIM number), 1 Business Whatsapp (SIM number)

Whatsapp backup data is visible in 2 different locations, once in iCloud Backup and in iCloud itself, although the 2 backup sizes are different. If I manually chose to backup Whatsapp nothing happens. Business Whatsapp only shows data in iCloud Backup. Manual backup works normal.

Screenshots for reference. For now I use a third-party app to backup Whatsapp, just in case.

iCloud - Whatsapp backup data, no Business Whatsapp data

iCloud Backup - data of both Whatsapp and Business Whatsapp

Manual Whatsapp backup stuck, nothing happening

Any guidance or advice? Thanks
