amp glue for yoast disappears in yost submenu

I updated yoast today and all the settings i made in amp glue for yoast are not working anymore. indeed thanks to this plugin my maxbutton became amp compatible (pasting custom css in the right place) and also my fa fa fa icons from Font Awsome could be visible in amp version thanks to this plugin (put link tag in the right place)

now nothing is working anymore, no amp submenu in yoast menu, thus no way to go and check if my css and link tag is still there. now i am hesitating to unsinstall and reinstall i will lose all my settings for sure

any help about this ?

thank you in adavance
