Apologies for the delay. The issue with this SKU I believe is that it is part of a recursive kit. A recursive kit is a kit (kit a) where the component of the kit is a kit (kit b) itself, and that kit’s (kit b) component is the original kit (kit a). I’ve been looking into recursive kits and how to replicate them but haven’t been able to yet, which is the cause of this delay.
I’d recommend running a kit_clear mutation on this SKU and then try to use product_delete.
