ApolloClient Caching does not store every item

Question

I have a problem with ApolloClient Caching. There are a few items that are not stored in the cache.

Env: React Native

Packages:

• @apollo/client
• @react-native-async-storage/async-storage
• apollo3-cache-persist

Result (without Caching):

contentElements: [{
  __typename: "My_Stage",
  cta: {label: "Test", link: "mylink", __typename: "CTA"},
  id: "0123234234234234234234",
}]

Result (with Caching: strategy: cache-first)

contentElements: [{
  __typename: "My_Stage",
}]

I dont think this is a problem with normalization because the element has an id and __typename. I have also tried to disable normalization with keyFields: false for Stage but this did not work.

Let me know if i did not deliver enough information. Thank you for your help!
