No, you did nothing wrong. I get the same thing on my test environment, it's definitely an unknown bug yet.
In one of the previous versions there was a major change regarding the data presentation and it seems that I've either forgot to change that code, or accidentally break it.
If it's not an urgent case, I will release an update within 7 days that should solve this problem.Best,
