The EE box uses the same remote codes as the default codes of the Freesat box. This means that both the EE box remote and the Freesat box remote will operate both boxes whenever you use either of the remotes.
Fortunately, the Freesat box, and its remote, can be changed to use different codes, so that the EE box's remote will only be recognised by the EE box, and the Freesat box remote will only be recognised by the Freesat box.
If you are using a non-original Freesat remote, then this will mode change is not possible, and you will need to obtain a genuine Humax remote for your Humax. Genuine Humax remotes are usually easily identified by the word "Humax" on the front of the remote in large letters.
