Why doesn't the "Advanced Attribute Edit" include my new block attributes?

I don't know if it is a setting that I've missed, but I've been following the tutorial on the DraftSight website in order to make new block attributes for my title block, and yet it won't show on this screen. I want it on this page to just be able to easily add the values all at one time.

The new block attributes are showing on the Block Attribute Manager page, but they just won't show on the Advanced Attribute Edit page. The new block attributes that I create have exactly the same properties than the existing block attributes that are on the Advanced Attribute Edit page. I have tried to sync the new block attributes from the BAM, but this has showed an "Error" in the command window. I have also tried to copy over the existing block attributes that are present in the Advanced Attribute Edit page whilst in edit block mode to be able to add more attributes in this way, again they appear in the BAM, but not in the Advanced Attribute Edit page.


Can someone please help me with this problem as it is stopping me finish a very important document!!


Thanks :)
