I have the wonder card, but as the card is not injectable (only the records are), you should:
1. Ensure your console attempted to receive wonder cards
2. Inject the items into your bag.
If your never connected to Mystery Gift servers or is banned (so unable to connect), the items won't work.
edit:
Technical details are.. the descriptions (and usage) of the item is added via the part of the Switch console that stores periodic game update data.
In other words, no game update = no Dynamax crystal functionality.
★And15 and ★And458 are for Larvitar and Jangmo-o respectively.
First image shows that I connected to network, so Larvitar crystal has function'
Second image shows that they have yet to add functionality for ★And390, so it's description is ???
