Why were these designs issued an 'Intellectual Property Refusal'?

I have been working on icon sets for some time now. Most of my sets get rejected due to "Intellectual Property Refusal," yet I fail to see any grounds for such a rejection. I wouldn't have minded if they had rejected them based on "similar content," but the current reason cited doesn't seem applicable to my designs.However, it is very difficult to accept that my designs are being rejected on the grounds of "Intellectual Property Refusal," especially since creating an icon set by hand is an arduous and time-consuming process. I humbly request the evaluators of Adobe Stock contributor designs to review and assess the submissions more carefully.I have been working on icon sets for some time now.

Even more frustrating is that designs created with such hard work are being rejected due to flawed evaluation. I hope you will look into this matter carefully.What distresses me the most is that, after working for six long months, I had started seeing some downloads over the past month, but for the last 15 days, I haven't had a single one; this is truly disheartening.
