I need help solving this Ravens matrix
Today I was going through the Mensa Finland IQ test and I came across this puzzle:
After finishing the test the first time i came back to the question and struggled to find a logical way to solve it. 30 minutes later i decided to test which answer was correct. I figured that knowing the answer would lead me to having an easy way to find the pattern but i still couldn't find it.
I'm very curious if anyone at all can find the logical pattern in this puzzle or if there is even a logical pattern to find in this puzzle.
I have a strong suspicion that it's actually a puzzle without an answer and the answer is just randomly picked from time period to time period.
Spoilers if you don't want to know the "answer":
Answer number 5 (bottom middle answer) gave me +3 IQ when i answer it instead of other answers, therefore i thought it was the real answer. I found a 2 year old post about the same question from the old "Mensa Norway IQ Test": Mensa web test question #34 Picture:
Notice how the answer options are different and answer 5 isn't even an option here, so there can be no way it's the correct answer. People in the post suspects that answer 3 or 5 is correct (in the old answers) but answer 5 (in the old answers) isn't even a part of the new answers for the Finnish test and answer 3 i tested and it didn't effect the outcome of the IQ test. I have run into this before with Mensa IQ tests, for example Mensa Norway puzzle 31 Mensa Puzzle 31: I got Answer B as the correct answer with multiple tests. Some people support that B is the correct answer and gives more score while some people claim that D is the correct answer and gives more score.

Does Mensa include puzzles which are insolvable in their tests so people will waste their time on them and get a lower overall IQ or am I just mistaken?
