to see the suggestions for your Watch List, you would select Suggestion under the My Wikitree drop down list. When you select it under the Wikitree ID menu on a profile, it gives you the suggestions for that profile and the 'ancestors' of that profile, but you are not responsible for all of those.
Sometimes that Suggestion is caused because there are 2 related people, such as father and son, so the one that doesn't match the page needs to have the Find a Grave template added with sameas=no
Other times, the same Find a Grave page is referenced on 2 profiles that should be merged or possibly it has been added to a profile that it should not be on. Comparing the 2 profiles mentioned in your question and the Find A Grave page, Crosse-15 has the same dates,but the birth location is different (biography states birth is biography but the location at the top of the page has England). It has the same parents and wife, but there i no gravestone so that also makes everything somewhat questionable and not necessarily reliable. Crosse-49 dates do not match, but they could be the same person. Biography in Crosse-15 mentions 2nd wife is the wife in Crosse-49. Crosse-49 states he couldn't be married to Rachel at the same time. The children on both profiles are born about the same time, so there is a problem with those profiles,
