Hi. This usually happens when the layer's names are not the same in component variants, but they should. Can you show a layers of your component or a link to the file?

Is this capture enough?

Seems like i didn't correctly understand the issue at first. I thought you needed to change the text in the second variant while hovering, but it seems like you need to change first card to second while hovering and the text in the second variant should be different each time, am i correct? 

ok. Then i need a new variant about hover variant, and there add a property text. Right?

You need to put this text in Default state as well, but with a 0% opacity and add a text property. Here is an example ↓

Wow. You're wonderful. Thank you so much for your help. I think it's much clearer to me now. That's what I needed. I must practice much more. 

Thanks
