I fixed the issue by installing a patch.

Run the following commands from inside the explorer folder to install the patch.

wget https://raw.githubusercontent.com/walletbuilders/iquidus-x11-patch/master/iquidus_x11_patch.diff
patch -p1 < iquidus_x11_patch.diff

The content of the patch is visible on the following page:
