AEM6.3 not able to add properties under /etc/tags
Hi ,
We had upgraded from AEM6.1 to AEM6.3 and We find that in standalone AEM6.3 under /etc/tags there are few properties like [sling:resourceType ,languages, sling:target] and which i would need to add under the upgraded version of AEM6.3 else edit tag in touch ui does not work
I am not able to add new properties like languages under /etc/tags using crxde .Below is the snapshot for the same.
Any inputs as how i could solve the issue


Thanks
