Finder extension losing resources to show badges

Hello there,

I am developing application with finder extension, my problem is following :

After freshly starting application, or restarting finder itself, the icons are correctly there and working.

After a short period which is always different, its like extension is losing resources to display the badge identifier in the finder window, i debugged the workflow,

i m setting up the correct icon, just finder ignores the request. This problem appeared in High Sierra first.

Also until now, the icon update was working aswell - now when i first time add icon to a file/folder it works, but the change after is displayed just when i manually move out from the folder, and in again.

I will appreciate any answers about extension.
