Can't find star to mark contact as Favourite

[Android Central Question]

I have a Samsung and have been able to favourite two of my contacts but the third one has no option. I looked at https://forums.androidcentral.com/samsung-galaxy-s7/744723-cannot-add-favourite-contacts.html#post_6348985 but none of the suggestions helped.
Any further ideas? Thanks

Welcome to Android Central! Do you have a Galaxy S7 as well, or some other Samsung phone?

Is the third contact saved to your Google account, Samsung account, or local Phone account?

I have a Galaxy A02s. The contact is saved to SIM1 only. I thought of re-entering the contact but don't want to lose their messages & WhatsApp history.

I think it has to do with the fact it's only saved to the SIM card. Can you import it into your Google or Samsung account?

I added the number to Google and it worked but I now have a duplicate contact and I'm worried that if I delete the first, I'll lose previous messages...

Look in the Contacts app menu for a Merge Duplicates option.
