I've installed Craft Personal 2.5.2763, and have set up my own simple blog.
For each Entry in the Blog Channel, I've set up an Asset Field, which is used for the header image displayed on the blog entry template.
I'd like this Asset field to be optional, as I'll be displaying a default image if one isn't defined in the Control Panel.
Adding an image to the field works great, but I'm seemingly unable to remove it once it has been assigned and saved when I go to edit the Entry and click the "Remove" icon.
When clicking the Remove icon, The image disappears from the CP edit page as you'd expect, but when clicking "Save", it seems the removal of that image is not actually being saved, as it is still there when I go back in to edit the Entry.
UPDATE: I've also found this issue on a normal Text field too. If you set the Text field to some data, save, then go back to edit, delete all text, save, then the data is not removed and the original data remains.
Am I doing something wrong, or is this a bug?
Thanks in advance for any help.
