I'm having some oddball things happening with my sitecore environment's experience editor. We have a pretty basic layout - one single placeholder named 'content', where we can add multiple components/renderings.
We have a single Master Layout that has a standard @Sitecore.Placeholder("content") and we have the placeholder defined in /sitecore/Layout/Placeholder Settings where the placeholder key matches 'content' and we have a limited amount of controls inside here, and all of that appears to be working fine.
I created a new blank page (using the master layout), and I add datasource items (using the appropriate templates) and update my presentation details with the appropriate controller renderings, I am able to see all of my components like expected.
The moment I open the experience editor to add new components, I click the "Add new components" icon, and my + Add here tags are displayed above my modules in an "empty placeholder" which is also named "content", and I can't add components between my other components.
It's as if the items weren't added to the placeholder appropriately. Some pages appear to be just fine, with (Add Here) icons displaying correctly between modules, and some don't. I'm trying to figure out how the experience editor is determining where a placeholder really is and how it's deciding where to add the (Add here) icons.
One thing I noticed is that I'm unable to move/delete the components I've added in the Content Editor. Has anyone ran into this before?
