Windows 10: I cant see any other cores but only 1 in msconfig boot advanced settings

I have amd ryzen 5 3550h with 8 cores. But my task manager is not showing that. I can see how many cores i have in device information. And i saw a solution for it from microsoft communityin this. But i opened my run and then type "msconfig".Then select boot and then advanced settings. But i cant see any other core above 1 to select. In the first time it show me other numbers of cores, I accidentally select 1 core and apply then restart.Then it never show that other core option to select I think its a silly problem But..... I can't fix that. Please help me if you know the solution for it. I think my english is so bad. Sorry for that.
