I'm not 100% sure about all of this, but I most definitely have added keyword Amazon capsules, seen them on the page, hit "Done Editing" and had them disappear. When I go back, the capsule is there, but it is empty - no keywords.
I MAY have seen the same thing with text capsules, but I am not certain of that.
I THINK the problem comes from haste - not waiting long enough before hitting that "Done Editing". Because of that theory, I have begun using Preview before I click that - if my changes are not there (even though they are on my editing screen), I wait a few seconds and try again. The stuff is usually visible then.
Again, I am not CERTAIN of this but offer it as a possible explanation for mysterious disappearances while editing hubs.
I have had it happen with text, and it was a result of me, clicking the wrong button. 'done editing' before 'save'. something like that. I have no idea if that is relevant, but I hope you get it sorted soon.
