Distinctive ring

[b0b]

I have 1 main number and 2 virtual numbers. I was able to assign distinctive rings to each of the two virtual numbers.

Then I assigned one of the virtual numbers to my cloned line. Now the virtual number on the cloned line rings exactly like the main line.

How can I get the second line to ring differently like I could when it was a regular virtual number?

Thanks in advance for any help.
