This question has nothing to do with TubeBuddy nor it's something regarding or related to TB features, that being said, I have moved this question to YouTube Discussion.
Furthermore, the watch hours you see in your Analytic include all the watch hours which are of private/public and unlisted videos of long-form and shorts form and If you're seeing 4 hours of the watch hours in your last 365 days period range, it basically means either you have a shorts video or a long video which you have either private it after publishing or it's a short form video or whatever. Still, it's not eligible for monetization.
The above could be a possibility, the other possible reason is, If you have not deleted any video or have private or unlisted them or If it isn't a short video then you need to wait until the said hours can be shown in the monetization tab. It usually takes 24-48 hours and sometimes it at as well ends up taking 72 hours, it depends on the lag from the YT end.
Regardless of the above reasons, unfortunately, we can't do anything from our end, it's something you need to check with
TeamYouTube On Twitter so that they can get this check from their end If you believe there's something wrong with it.
P,S If you can link your channel on your signature or below your profile so we can check your channel out and that might help us a bit to understand what might be the cause of such issues. I have pasted the instruction as to how you can do so below.
