Hey there @dash2000

 

I'm sincerely sorry for the inconvenience, I'm afraid that this is an intended feature

 

The only ability ferroseed can get is Iron barbs, but when evolved into ferrothorn it gets access to Anticipation as its hidden ability. Consequently, there's a slim chance of getting the hidden ability and since ferroseed can only have iron barb it wouldn't be displayed to you until you evolve it. Getting a pupitar with the hidden ability is a similar case where you won't be able to know if you have the hidden ability until evolve in their late stages. The ferroseed you had in your possession had the hidden ability and this is why it has anticipation now

 

I hope I was able to answer your question, let me know if you need more clarifications

 

Have a splendid day!
