The bug is that the command does not allow users to put fullstops into individual instruction.
If the user has a fullstop within one of the instruction, the command automatically splits the single instruction into 2 instructions, even if the user intended for it to be a single instruction. This was not highlighted in the user guide which might cause users to be unaware.
