It might be because you have a invalid cq:LiveSyncConfig node.
For example
In CRX/DE take a look at the properties on the cq:LiveSyncConfig (/content/we-retail/en_ca/jcr:content/cq:LiveSyncConfig) node. Does this node have the correct configurations?
- cq:isDeep == {{Boolean} true
- cq:master == {String} /content/we-retail/language-masters/en
- cq:rolloutConfigs == {String[]} /libs/msm/wcm/rolloutconfigs/default
- jcr:primaryType == {String} cq:LiveCopy
if these configurations are there, then you should be able to see the options that you have provided above. For full instructions on how to fix the cq:LiveSyncConfig node, click here https://sourcedcode.com/blog/aem/how-to-re-sync-a-live-copy-language-root-to-a-blueprint-in-aem-msm
