Button images disappear after selecting a button from the skills panel.

Specifically, the buttons work as intended, they still function however their images no longer do once I use a specific skill. I use this exact set up in my other game (on hiatus) and it works perfectly, the attacks come out and when the unit reaches back to the top of the processing bar the buttons appear.

Below is a preview of how its supposed to look

Below is what happens after I select and use a technique

As you can see the button images don't appear but I can assure you they're still there and fully functionally but I'm wondering if anyone has any idea as to why this is happening. I've never had this happen with the other game which has the exact same set up so I'm beyond confused. Thanks in advance and here's a snippet of code which shows what happens with the skill window active and with the skill window inactive. And I know it works properly but maybe someone will see something I don't.

 {
                     if (skillwindow.activeSelf == true)
                     {
                         Attack.SetActive(false);
                         Defend.SetActive(false);
                         Wait.SetActive(false);
                         Technique.SetActive(false);
                     }
                     else
                     {
                         defendstatus = false;
                         Attack.SetActive(true);
                         Defend.SetActive(true);
                         Wait.SetActive(true);
                         Technique.SetActive(true);
                         ButtonManager.unitid = id;
                         currentstate = UnitStates.Idle;
                     }
                 }
