CCKExtraFilterConfig is overlapped with collapsed VABOrganizer list

[Gordon-Dry]

RP-1 adds just one @CCKExtraFilterConfig, by GameData\ModularLaunchPads\Category\Category_CCK.cfg which does:

@CCKExtraFilterConfig
{
	Item
	{
		name = Modular Launch Pads
		tag = cck-modularlaunchpads
		normalIcon = ModularLaunchPads/Category/MLPnorm
		selectedIcon = ModularLaunchPads/Category/MLPselB
		usedByMod = Modular Launch Pads
	}
}

When I open this entry, in background the collapsed list of VABOrganizer is still visible. This hurts the eyes, trying to find proper LC parts for the vessel.

I also use https://github.com/Cruesoe/VABOrganizer-RP-1-Configs - but I don't assume that configs could be the issue. It most likely is the code of the mod.

After closing the CCKExtraFilterConfig entry (MLP) by clicking on its icon, the collapsed list occurs and clicking on it does nothing, as the according CCK "Filter by Function" - "Engines" subcategory is not opened anymore:
