There is no setting to change the appearance of ‘Share This’ buttons found in page or post footer.
You will need to click on the last “right angle arrow icon” which is the more options to reveal a webpage of all other options which includes linkedin and reddit.
By the way, the function to produce these buttons are found in evolve-plus/library/functions/basic-functions.php at line 1471. Which is produced by function evolve_sharethis()
You can contact our developers, ( https://theme4press.com/theme-customization-service/ ) if you want to add linkedin and reddit before the more options right angle arrow icon.
