MFN listings are automatically suppressed when going live

Recently, I have listed two brands via MFN and have found that many of the listings are suppressed immediately for no reason. It does not seem to be an issue of handling time or pricing. We have filed cases and Amazon is claiming our account is in good standing, but there may be an issue with the brand itself. But after it happened twice, it seems very odd. We are added in Brand Registry for both brands.

Has anyone seen this happen before? Is there a way to correct the issue?
