This is a bug. Sometimes the parent-child relationship of the Integration Folders/Components can be screwed up for unkown reason.
Only known way, to fix this is to use Document Type Editor (DTE), which wM does not recommend to use.
If you are familiar with DTE, you can edit the relationship. But, be careful you can really screw up if you don’t know what you are doing.
Take backup of everything from EI, DTE before modifying anything in the DTE.
