DNSSEC error parsing in zone editor

Hello,
Today i need your help.
I just installed DNSSEC on one of my domains. Everything went well, my checks are all ok.
The only problem I encounter is when I want to edit my area with WHM. It makes me a parsing error:

zone example.com/IN: loaded serial 2017122833 OK Unable to parse zone: There was an error while loading the zone for example.com. Please correct any errors in this zone manually and try again. The exact error from the parser was: : []

I searched for long hours to determine the problem and I came to understand.
In the dropdown lists of the editor, there is no DNSKEY record type, so the editor gives an error because it's an unknown type of record.
Do you have an idea to solve this?
Any help will be welcome.

 

For better understanding,
In my zone file "example.com.db"
below the SOA record, I included the 2 keys
$ INCLUDE "/var/named/Kmykey.ksk.key"
$ INCLUDE "/var/named/Kmykey.zsk.key"

and after I generate a signature that gives me a signed file.
And in these .key files, these are DNSKEY records.
By controlling the WHM editor, it does not propose DNSKEY records.
