Startup Disk Creater 24.04

[Grizzlly]

Hi

I have a question, I was trying to make a few PuppyLinux live disks (for my 
less powerful laptops)

I started Startup Disk Creater on 24.04
choose NoblePup32.iso (353.280 kb) as source
choose an SdRam card as destination
all went well and compleated
reboot from sdRam
and got not NoblePup32 but a full Noble-Live-64 session

I (re)started Startup Disk Creater on 24.04
choose NoblePup32.iso (353,280 kb) as source
choose a USB-Stick as destination
all went well and compleated
reboot from USB-Stick
and got not NoblePup32 but the same full Noble-Unity-64 Live session

Okay NoblePup32 is only at RC stage so I trie dwith an older JammyPup32.iso

I started Startup Disk Creater on 24.04
choose JammyPup32.iso (377,856kb) as source
choose an USB-Stick as destination
all went well and compleated
reboot from USB-Stick
and got not JammyPup32 but the same full Noble-Unity-64 Live session

when I choose each pup.iso as source StartupDiskCreater did show size as 3.4Gb 
which seemed odd, I don't have the Noble-Unity-Desktop.iso one that drive

fearing I had (somehow) downloaded the wrong iso's I mounted these (on Noble)
FossaPup32-9.5.iso (418,816kb)
JammyPup32.iso (377,856kb)
NoblePup32/iso (353,280 kb)

went thru the readme & distro-specs of each, all look correct for the versions 
of *pup32 they should be

did I mistake how StartupDiskCreater (should) work?
