Frontend remove attachment button seems to remove all attachments (in reality no)

[Heklaterriol]

In frontend events/venue editing:
When there are several attachements, each one has a remove button.
If you click on jus one of them, all attachemnts are removed, not only the one assigned to the remove button

i tested, it only looks in editevent like this, when you save and look into event details, only the removed attachment is away!
But it is true, it would be better, when the other attachments would rest visible even in editevent (before saving)

But anyway, it would be good to have a notice in edit.php
something like:
<?php echo Text::_('NOTE: All CHANGES will only be fixed after SAVING! '); ?>
