Count property prompts for unit of measurement

[johnjohndoe]

One of the properties in my .csv file contains a count value (column "partikelPM10Ueberschreitungen"):

So I have chosen "Measured Value" and "Count".
Then later when the wizard hits step 6b "Unit Of Measurement" I am forced to choose a unit for the mentioned column as shown in the screenshot:

Do I misunderstand what "Count" should be used for? Or is this a bug?

@EHJ-52n, @CarstenHollmann Any comment on this issue?

[EHJ-52n]

It seems like a bug. Could you please provide a minimal example csv and attach it to this issue by pasting it into a comment.
In the end, it should not be a problem, as the feeding code doesn't need it. Could you check this, too?

Here are a few sensor samples.

I would recommend to split your csv file because the importer will not be able to handle the different number of columns, or is each line an example from a different csv file?

The file contains multiple sensors (see sensor_id column). Each sensor (row) has the same number of columns. There are rows which do not have a value for a certain column at a certain time.
