You could just take Adsense off that one page, if that's the only one getting the clicks. And then discuss it with Adsense. If you are making over $25 per month you can get email help from Adsense.
There are a number of possibilities for the self referral.
1. You're producing this in your site yourself. Self referrals happen for a number of reasons. The most common is when a page is missing the Analytics tag. Say you have a page called cats.html. If someone goes from the SERPS to cats.html, no visit is recorded as landing on that page from the SERPS (because you've missed out the Analytics tag). When that visitor goes to another page on your site, because they are already on your site, the next page will shows the visit as a self referral. Google has a lot of information about self-referrals here. https://support.google.com/analytics/answer/6350128?hl=enhttp://www.gachecker.com
shows all the pages on your site have the Universal Analytics tag.
2. There is a real bot that is visiting your pages, but it has altered the referral field to show your domain name. In this case, I'd expect the visit to show up in your SBI traffic logs. This is because there is a real visit going to the SBI servers. However, SBI probably filter out internal referrals, as they only want your stats to show you external visits.
3. Someone has sent this data independently to the Google servers with your Analytics ID. Google thinks it's coming from your site, and adds it to your reports. This is how referral spam happens. There's a lot of this around, which doesn't instill confidence in the GA stats. Usually, the added data contains a link to a 3rd party site to which they want to drive traffic. These visits don't show up in SBI logs because they are "ghost" visits - they don't actually exist. No one goes to the server, it just looks like they do.
I can't read your screen shot, so I'm not sure if this is directly affecting your Adsense. The Adsense problem might or might not be not be related to the self referrals.
I also found someone who had the exact same problem here.https://webmasters.stackexchange.com/questions/105535/what-is-adding-p-subid-and-uid-variables-to-the-query-string-of-a-site-url/105629#105629
However, there is no mention of how he resolved the problem.
