Sidebar isnt showing recent widgets

Hey everybody I had wp-Wall on my Site and it had messed up my home page so it didn’t show any newly added widgets in my sidebar. I deleted it and now it is still there and my newly added plugins and widgets are still not showing up this did just happen and i’m going to give it some time. Hopefully It’ll update or something again it is only on my home page all other individual pages are okay. Maybe it changed my themes index.php? should i reinstall the theme again?

Thanks
