Addons Cannot Be Uploaded to Realms

When trying to upload addons to a Realm, it starts the process and goes to the "All Done!" tab, but it shows that 0.00mb were uploaded. This has happened with every addon I have tried to upload. 

 

Steps to Reproduce:
1. Click on the edit button on a Realm.

2. Go to the addon section and apply a addon.

3. Click the back button to apply the changes.

 

Observed Results:

Clicking the back button triggers the game to try to upload the addons and sends the player to the "All Done!" page but no packs were uploaded.

 

Expected Results:

Clicking the back button uploads the addons to the Realm and the "All Done!" page shows the amount of mb uploaded correctly (not 0.00mb)
