"Remix" broken for 2 Discover modules

[jame5chia]

In ArcLab Discover (https://builder.arclab.io/discover) - clicking "Use Template" green button on any module's modal opens a copy of the respective ArcLab Discover module in a Builder's Editor page.

There are 2 modules that this is broken:

1. Customer Service - Professional Image (Learn module for ref: https://learn.arclab.io/?nano=64f837136563fda925be5df2)
2. Customer Service - Handling Feedback (Learn module for ref: https://learn.arclab.io/?nano=65027979443b187cf374974e)

Could we investigate?

Steps to replicate:

1. Go to https://builder.arclab.io/discover -> Learning Library will load
2. Scroll down and open either of the 2 modules above.
3. Click "Use Template"
4. See error
