vAT reverse-charged in the Netherlands, but Belgian address

I purchased something from a supplier that has both a Dutch and a Belgian vAT number. The invoice shows 0% vAT, so I think I can view this as an invoice from the Netherlands with reverse-charged vAT. However, both vAT numbers are stated on the invoice, the Dutch and the Belgian ones, and only the supplier’s Belgian address is stated on the invoice. So the invoice shows a Belgian address, a Belgian vAT number (as well as the Dutch vAT number), but the vAT has been reversed, 0%. How is this possible, is this correct and how do I correctly report this in my expenses? Thank you!
