Please some hints, why these were rejected

Hello and thank you for your attention,

I am quite recently author to audiojungle and got 4 of my first 5 tracks approved. One was rejected, with reasons I understand.
Last week I uploaded three more and all of them were rejected as well as for mixing reasons as for not being compatible for the purpose suggested.
I attach the previews here, because I cannot follow the reasons so far in this case.
Any hint or help is appreciated. Thank you in advance.
