Try to place a slab as indicated in the screenshot and it will vanish.
I think this was to do with the security thing that @shoghicp added? Sorry for not being specific, but I seem to remember something like this being on the olod forums
Well, singleplayer has the same issue, you can only place them when tapping a block side (in your case the iron block at the right)
This is an issue with Block->getSide() on the inner-half face of the slab returning the _next_ block. If the block in the next space is not replaceable, this bug will occur.
I remember this one when I first started playing factions on PE servers. Can't believe no one has fixed it yet ._.
@Muqsit welcome to my world...
This has been fixed on a development branch and will be closed when the fix is merged to master (no ETAs will be given).
