Qt design studio warns about incompatible Qt Library which i'm not using

I'm using Qt with version of 5.15.2,and compiled some c++ classes as DLL and registered as a custom module to qml engine.

When i import my custom module in the Qt Design Studio,The "Text Editor" shows about "Read typeinfo files successfully",but in the "Navigator",it warns about "found not working imports "***.dll" uses incompatible Qt library.(5.15.0)[release]"

My qml files that imported my custom modules can works well when i load them with QtQuickWidget and i can use my custom module normally in "Qt Creator"

I have only one version of  Qt 5.15.2 installed on my pc and i have tryed different versions of "Qt Design Studio" with 2.2.2,4.1.1,4.7
