cartography table 1st slot broken (fixed, im just a dumb bedrock player)

Can you place a map in the first slot?

no i cant. it wont allow me. ive used it before but now it wont work

i found that i can place a non blank map there, but no paper there, so i cant create maps there. wait nvm its not a feature.
