Unwanted arrow present

[nmsutton]

In Ubuntu 20.04 for some reason an arrow is appearing on the right of my dock icons and when pressed it reveals some hidden icons and hides others. As seen in the screenshot below there is plenty of space for the hidden icons (6 were hidden) but the dock hides them anyway. Please allow for an option to not hide any icons.

What are your settings here?:

@Golddouble in my DockBarX, the applet preferences button is greyed out and inaccessable, as seen circled in red in my screenshot. Therefore, there is no preferences window available to me, unlike in your screenshot. I am using DockX 1.0 beta on Ubuntu 20.04.
