Volatility Indexes not able to add data series

[DJ888]

Hi guys,
For some reason I have been able to add the COR90D index using Kinetick and CBOE as the exchange and using COR90D.XO as the path finder for Kinetick but when I try and add the following instruments the same way they don't show up in my "index" drop down list once added correctly to the instruments list:
COR10D
COR3M
VXAPL
Let me know if there are any logs or screenshots that may be of help to you in solving this issue.
Many thanks,
Adam.

Hi again, I've found a workaround - I've added them manually to the instrument list and now have them available in the data series drop down so all is well in my world now - thanks anyway!
