Answer 1

Try to run this command:

bin/magento rm -rf generated/* var/* && chmod -R 777 generated

Answer 2

This issue is down to the extension you have installed not setting the correct tab ID within the extension if you go into the etc/adminhtml/ folder and edit system.xml just below the variable you should see something like

<tab id="vendor_name_here" translate="label" sortOrder="10">

if there is on make sure that the options are associated to this tab. can you advise on the extension in question so i can take a look at it
