A work around is to simply disable the ssh app layer module:

app-layer:
  protocols:
    tls:
      enabled: yes
      detection-ports:
        dp: 443

      #no-reassemble: yes
    dcerpc:
      enabled: yes
    ftp:
      enabled: yes
    ssh:
      enabled: no

Alternatively, it can be set to 'detection-only'.
