Parquet2: Reading parquet files with varying sensor names

Hello!

It is a tad difficult for me to make a MWE for this, so I will see if my explanation with words can do it.

I noticed that if I have a folder consisting of multiple parquet files, but with different data, for example:

ParquetFile1
- X
- Z

ParquetFile2
- Y
- Z

Then it would only give me the two sensors, X and Z, and not the sensor Y. Is there an issue in the sense that Parquet2 struggle to read parquet files in the same folder with varying format?

Kind regards
