Hi, @GHETH
Thanks for posting, and welcome to the Roku Community.
We understand the issue you have encountered with the subtitles on Crave that do not work properly. For this matter, it's best to reach out to Crave's support directly and let them know about the issue you have experienced with their app. The issue is related to a subtitle; thus, it's part of the app's functionality, which the channel provider can address. Most channels on Roku are designed and developed by the channel provider.
We hope for your understanding in this regard.
Best wishes,
Kash
