You can have duplicate pool types with different CKs. This due the way we choose the pool type.
For example, if you have 2 CKs, one with [Anti Bot, Anti-Virus, URL Filtering, Anti-Spam, Email Security] blades and one with [Anti Bot, Anti-Virus, URL Filtering] blades, by definition both CKs should be under VE-NGTP type, but they don't share the same blades.
In this case, we will have 2 rows with name VE-NGTP, each with different CKs.
If you wish there will be only a single pool please work with account management to create licenses with the same charectiristics.
