Material Skin not showing the queue controls on my Desktop PC

i) Just stumbled across this fine new interface for the Squeezebox Server. I've now installed on my Raspberry Pi 2, But for me, I can't see any of the Queue controls i.e. clear playlist , save playlist, as shown in the manual on page https://cdn.statically.io/gh/d6jg/ma...QueueArea.html

I seem to have only 'no shuffle' and 'no repeat' So at present this isn't useable for me as I can't add or remove albums as I see it .

I might be doing something wrong but have the remainder of the intereface apparently working as it should do.

Version: 8.3.0 - 1667251155 @ Fri 04 Nov 2022 09:16:39 AM CET
Hostname: raspberrypi
Server IP Address: 192.168.1.1xx
Operating system: Debian - EN - utf8
Platform Architecture: armv7l-linux
Perl Version: 5.28.1 - arm-linux-gnueabihf-thread-multi-64int
Audio::Scan: 1.05
IO::Socket::SSL: 2.060
Database Version: DBD::SQLite 1.58 (sqlite 3.22.0)

Can anybody give me some advice as to why this might be the case. I admit I've just installed but expected the controls to bre present.
Thanks in advance for your assistance.

ii) I can't find a way to remove Material Skin ? The server setting option doesn't appear to be preset in settings ? Removal should be indpendent of the the plugin perhaps as any poor behaviour now prevents me from reverting to the vanilla / stock player. Hoping this can easily be resolved.
