Invoice number in SLM

Hello,

So we have been using ALM  but for software licensing for years but are moving to SLM. I am working on importing my license records.  I noticed that when you export a license record from SLM, there is a field for Invoice Number, but when in the console, there is no such field.  Has anyone noticed this? Is it something on our end? Also is there a way to add any columns in the license view?

Any help would be greatly appreciated.

Thanks

Lisa
