Plugin adds “a[data-mtli […]” underneath files

I installed MimeTypes Link Icons on one of my websites. Unfortunately there seems to be a bug. After adding two files to a custom post type, there is a line of text added “a[data-mtli~=”mtli_filesize1,37MB”]:after {content:” (1,37 MB)”}a[data-mtli~=”mtli_filesize1,73MB”]:after {content:” (1,73 MB)”}”. How can I get rid of this?

I am using the latest version of WordPress with the Jupiter X theme and Elementor.
