Why is PackageType CUSTOM or UNKNOWN

Hi all!

We’re running an A/B-test with a monthly subscription and two pricings both pricings and have the same setup in the AppStore and RevCat but the second package has PACKAGE_TYPE  CUSTOM or UNKNOWN whereas the first has MONTHLY as expected. What could be wrong with the setup?

currentOffering.availablePackages.map((pkg) => {
let priceTag = pkg.product.priceString;
switch(pkg.packageType) {
	case Purchases.PACKAGE_TYPE.LIFETIME:
	  priceTag += ' einmalig'; break;
	case Purchases.PACKAGE_TYPE.ANNUAL:
	  priceTag += ' pro Jahr'; break;
	case Purchases.PACKAGE_TYPE.SIX_MONTH:
	  priceTag += ' alle 6 Monate'; break;
	case Purchases.PACKAGE_TYPE.THREE_MONTH:
	  priceTag += ' alle 3 Monate'; break;
	case Purchases.PACKAGE_TYPE.TWO_MONTH:
	  priceTag += ' alle 2 Monate'; break;
	case Purchases.PACKAGE_TYPE.MONTHLY:
	  priceTag += ' pro Monat'; break;
	case Purchases.PACKAGE_TYPE.WEEKLY:
	  priceTag += ' pro Woche'; break;
	default: // UNKOWN und CUSTOM
	  priceTag += ' pro Monat*'; break;
}
