Power KPI Matrix: Can't set comparison value

Hi.

I've been facing some problemas with the Power KPI Matrix custom visualization, where I just can't set the comparison value at all.

I've followed the steps on the "manual", where I edit the visual through the ... box, set each measure to the correponding comparison value and click on Apply. So far, so good, as the preview shows the visual as it should be (with the comparison value and the indicator that I've set up). The problem is that when I choose / click "Return to report" all settings are lost, and no comparison value is shown. I tried hiting [ESC], but then the visual bugs out, minimizing the edit section and preventing me from actually exiting it (I need to delete the visual and start over).

When I try to edit the visual again, it's all blank, as if I've never done anything before.

I believe that it is a problem introduced by some new version of the Power BI Desktop (mine is version 2.64.5285.741 64-bit), as it worked before. Unfortunately, I don''t know when it started to happen, as my previous reports (already set up) works (but I can't enter the edit section anymore, as entering it clears the comparison values).

Is there any workaround for this problem?
