There seems to always be a singular leading space on summer drop related items and entities' name. This can be seen on multiple instances, i.e. items' name on inventory, hotbar, entities' name on command output, and more (see the image attachments).
This is likely caused by the spaces inserted before a comment-like syntax in the language file:
