Hi--I have several hub sites and one of them in particular is having a strange problem. When I edit the summary on the items page (next to thumbnail) and save it, it only lasts for a couple of hours, or maybe a day at most, before reverting back to the default text, i.e., "Create your own initiative by combining existing applications with a custom site. Use this initiative to form teams around a problem and invite your community to participate." I attached a screenshot to illustrate where I'm talking about. Any ideas on how to get it to stick?
