Giving some context will help. But.... I've been playing with KiCad. On KiCad, R<some number> will be a label. It distinguishes one register from next. XX would be a value. When I build a schematic in KiCad, or any Cads really, it would assign label but you also have to update it with the value. It's up to the user to do it. If you forget it, I'd get ?? but on some other system would be XX or even nothing.
Looks like someone forgot to update it.
I know you are new to this site. Everyone is very willing to help. More detail you give, more you get back.
