Sterling, the disconnect may be that you have added your uncle's AncestryDNA test to the profile of Robert Andrew Calvert, Sr. (Calvert-4571), your grandfather born 1894, not to your deceased uncle's profile, Robert Andrew Calvert, Jr. (Calvert-4581). You can view the test information that has been entered for Robert Senior here. There is no DNA test information currently entered for your uncle, Robert Junior.
The only DNA information we enter at WikiTree into that dedicated DNA section is information about a test the individual actually took. We see numerous instances of people mistakenly adding their own test information to an ancestor who died before consumer DNA testing was even available, and that's an error. It distorts the resulting picture when WikiTree propagates the possible DNA relationships around the tree.
As a result of placing DNA testing information on Robert Senior's profile, if you check your suggestion report you'll find an Error 151 ("DNA Test on person dead before the tests were available") as well as two Warning 313 ("Missing mother's/father's DNA confirmation").
Since Robert Junior is your maternal uncle, you can use his test info--if placed properly on his own profile--to mark your mother as "Confirmed with DNA," but you can't set the same status for your father because there are no other tests recorded on your patrilineal line. It always takes at least two genetically-related people having taken DNA tests to set a "Confirmed with DNA" status.
For more information about WikiTree's "Confirmed with DNA" procedures, see https://www.wikitree.com/wiki/Help:DNA_Confirmation. It's worth noting that the "Confirmed with DNA" status also requires a source citation with rather specific language to be entered on the profiles involved.
Hope this helps!
