After ES update default user cover photo is changed. Override not working

Hello,

Everytime you update ES the default.jpg gets overwritten with som strange image you include in the build in /media/com_easysocial/defaults/covers/user/default.jpg

I tried creating an override in
/templates/protostar/html/media/com_easysocial/defaults/covers/user/default.jpg
but that does not work.

Please advice how to set an override, because it is very annoying having to check and update all these files everytime ther is an update.
