This is also a problem of Junior I asked Amir Ban by email and he simply refused to answer about these questions(at least he replied my email that is better than simply ignoring it so I know that he got my email and my questions). I was interested to know if there are other engines with similiar problems so I can guess better the reasons that Amir does not fix the mistakes of Junior(they have small but still positive practical importance and people already posted games when Junior lost 1/2 point because of 2 of the problems).
