Unfortunately, level 4 of 4x4 does not have enough clues to provide a correct solution.

Hi,

All puzzles should have only one solution provided by clues, I think all puzzles are correct, and until now I have not found a puzzle that can't be solved, all puzzles are computer generated and tested but there can always be a bug.

This being said, here is the solution:

1) Start removing items using left clues and middle clues, you should get something like this:


2) Apply left clues and same column clues, you should get this:

 

3) Now you got a difficult situation here, the easy way to solve this is using the "try mode" (the beaker icon),  Start with the less number of items for example faces and start marking the correct items using clues, if you find a inconsistency then it means that you need to switch the faces. Start with the wrong face should be like this:


In this picture there is a inconsistency the scepter must be on the right side of coin, but there is already a paper in that position because of pear / face clue.

4) So the solution is to switch cases and solve the puzzle:



I hope this solves your problem and thank you very much for your input.

Using the try mode is optional and you can also infer new clues from existing ones, to try to solve the puzzle the hard way.

for example, the clues: coin >  sceptre  and sceptre > orange , will gives the clue coin > sceptre > orange.

Other clues like: pear | paper and girl | paper will gives the clues that the girl, pear and paper are at the same column.

Using this two clues we can figure out the girl position, the rest is easy.
