Hi there!
Sorry for the unwanted delay.
Thanks for the access. I have checked and the template you are using is not from us: https://prnt.sc/FPwEi18iHUuh
Your template provider has created some custom addon, and those are available with pro version of the template. So the pro marked addons are not from us, they are made and supied by your template provider, so contact them will be better in this case.
Here are some overrided addon list within the template as well: https://prnt.sc/k_gznyCrD-nj
You will find all of our default addons available in SPPB Pro from here:
