Location of bug: public server; in my tardis

Status: Unsolved (This Bug has not been fixed in the most recent Updates)

Description:I can't break the blocks in my tardis or break them but technically they are still there, all the slabs are put downwards

Sounds like ghost blocks, have you tried rejoining the server/restarting your game?

 the problem was solved, it took one of the creative staff to replace the blocks and slabs
