Omnibus show last lowest price as 0.00, reason unknown

[brzorza]

Hi,
I believe I have encountered a bug that is displaying latest lowest price as 0, but I can't find the case why.

It is on product with variants (that is only product type in this case), doesn't matter if it has one or more variants.
I thought that it may be because the variant didn't have price set in omnibus field, but I have found a product that also didn't have this price set, and last lowest price set was displayed correctly.

I couldn't find an email to discuss this more privately and the case is urgent as it is regarding Omnibus Directive
