I am using the latest version of BDS with some resource and behavior packs. All work fine except for one, mcaddon attached below.

Here is how I installed it:

1. Renamed the mcaddon to zip
2. Extracted the resource and behavior packs and put them into the respective folders, for both server and level.

BDS Automatically updated the applicable json files.

Is there anything different with this addon that prevents me from using it? Thanks.
