Trados Studio 2022 : alignment

I tried to use an alignment of an updated version of my translation to put it back to my project settings...I imported the alignment into a new TM because the settings did not accept alignment like that...but it does not work. The TM is empty...What can I do?

1 Isn't a function to use an updated version of a translation?

2 why can't the settings of my project accept alignment?

thank you
