Donations are only allocated to the projects in the dependency tree that have signed up with thanks.dev. In the Sentry list for example if you click the more link at the bottom you'll see all the projects that hadn't signed in. The ones showing verified next to their name signed in after the funds for this month were processed. I see how this is causing a bit of confusion and will work on improving this aspect asap.
If you're improving the UI around here it would also be good to see how the list was determined. For automated detection in particular it seems like the tooling used also should be made public to allow testing. I know of at least one dependency that I would expect to turn up on sentry's list that doesn't. (A first guess: a bug in how you handle Rust workspaces, using the root to calculate dependency depth; alternatively a bug in your handling of non-lowercase github usernames, I notice there are only lowercase usernames in the list, but that might just be an artifact of your UI design).
