Cascade delete warning when attempting to remove catalog item variable container start/end

[kevinanderson]

I am attempting to update a catalog item, and change the presentation of the variables to work better with the style updates that came with Geneva.

I notice that whenever I attempt to remove a variable of container start or container end, I get a cascade delete warning for a very large amount of variables and options.

Why does this occur?   I don't think that deleting a container start or end variable should effect anything.

Is there a way to turn off cascade delete for this variable type?

thanks

seems the cause of the cascade delete warning is the RITMs that have already been created using this catalog item variable
