Comodo certificate doesn't have a name in Thunderbird / Firefox

It was alright whilst I had just one, but now I have three email accounts, each with their own certificate, it’s rather confusing - see attached.

I don’t see anywhere during the save / download / export / import where I can specify a name or title to use allowing me to differentiate between them.

I applied for them / opened the “retrieve your certificate”. This installed it in Firefox (with no name). I can then backup and import into Thunderbird, but no option to have a name.

Can this be fixed? Is it a glitch with the certificate or mozilla apps? I tried retrieving it with IE, but cannot, presumably because I’ve already done so with Firefox…
