Do gem choices become free after choosing it

I have a question
I read Dirty Dancing gem free the first time and loved it so much I saved up on gems so I can re-read it and choose all the gem options.
It’s been a while so I decided to read it again and I noticed that the gem choices don’t have the amounts anymore. Almost like they’re just regular gold choices.
If you’ve chosen a gem choice before and then re-read the story does it become free?

Yeah, they won’t make you pay for something you’ve already paid for.
