JOSM>Imagery menu order and contents - Don't use hidden country grouping in menu

[A_Pirard]

The Imagery menu list is no longer in sort order.
I used to add a small prefix to the names to get them in a meaningful order.
I just "Activated" 2 "default entries" and they stayed at the bottom.
I renamed them and I got 2 old + 2 new names at the bottom.
Also, what is that "(d.dddddddddddddddddddddd)" at the end of the names?

Any way to get rid of it?
Thanks.

I have half debugged this.
https://josm.openstreetmap.de/wiki/Maps/Belgium contains the definitions
SPW(allonie) 2012 aerial imagery contains <country-code>BE</country-code>
SPW(allonie) 2009 aerial imagery does not, I have removed it, now restored.
In the attached screenshot (bottom of JOSM>Imagery):
2009 was activated alphabetically
2012 was activated under a separator
2012 was renamed "BE ..." so that it be listed alongside other BE*s higher in the list
but it did not, it remained at the bottom, but above the separator

I finally grasped the undocumented per-country grouping.
But, as you see, it's surprising and inconvenient when one uses one's own alphabetical country grouping.
And getting double entries is weird.
Prefixing names with country code as I'm doing is much simpler.

The number in brackets is the zoom level. You bookmarked a layer using the popumenu. The result is loading always in same zoom level as bookmarked.
