Items indicated on your 1m-2m screenshot must be translated manually. This is the name of business process groups, so you need to go to System Settings - Business Processes - next to the group, click Configure
https://prnt.sc/10dk0ko and change the name in the language you need
https://prnt.sc/10dk11m - data items do not support multilingualism. Similar actions need to be done for the necessary names of business processes.
