ASUS RT-AX55 Apply button doesn't work on several pages

[Veoxer]

Hi, I just bought an ASUS RT-AX55 that I'm running double NATed with my ISP modem. Everything works great except for some pages where I noticed that clicking the "Apply" button doesn't do anything. When I check the browser's console for exemple after hitting the apply button on the Adaptive QoS page I saw the following error :

Uncaught ReferenceError: showLoading is not defined
    at submitQoS (QoS_EZQoS.asp:894)
    at HTMLDivElement.onclick (QoS_EZQoS.asp:1860)
submitQoS @ QoS_EZQoS.asp:894
onclick @ QoS_EZQoS.asp:1860

Firmware Version:3.0.0.4.386_45375
Is there anything that I can do to fix thid?
Thank you.

For any one facing the same problem in the future, the cause of mine was my adblocker that was blocking the progress popup from showing up.
