Reactivation Windows 10 Pro issue

I have changed my hardware recently and found that I can't reactivate Windows 10 Pro. In Reactivate Windows section, I can't find my current device in the list, only my old motherboards appeared ( MSI and Gigabyte ). My old hardware are I7-4790 + MSI H81M
Mobo + 8GB DDR3 Ram and I upgraded to I5-9400F + My new Asrock MOBO B350 or 450 something (Can't remember) + 16 GB DDR4 Ram. There is no my current MOBO in the reactivate section, only the old one appeared (MSI H81M Mobo). Pls someone help me.

Also note that I have signed in with my microsoft account that links with Windows 10 pro licence but it only shows the old mobo in the reactivate list.
