Here's what Vegas Pro 16 reports:

VEGAS Flash - 00000000-0000-0000-0000-000000000000 UID: {Svfx:com.sonycreativesoftware:flash}  isOFX: True - Soft Flash - 3

VEGAS Dissolve - 00000000-0000-0000-0000-000000000000 UID: {Svfx:com.sonycreativesoftware:dissolve}  isOFX: True - Fade Through White - 19

Certainly not much help. And I didn't see the numbers listed in your image in the list at all.
