Issue in readRowsByRange in DLMSReader Class

Hi,

I'm reading profile from several meters simulataneously by using readRowsByRange method in DLMSReader class, but the fetched data gets mixed in with each other. For example readRowsByRange return data from Thread1 fetching profile from Meter1 to Thread2 fetching profile from Meter2. you can observe in the below log excerpt that Received data only has 4 data points as parsed in the dlms translator but the cells size is 12. Does readRowsByRange not support parellel execution?

Code:
Object[] cells = reader.readRowsByRange(profile, new GXDateTime(start),
new GXDateTime(tempEnd));
LOGGER.info("size of partial fetched data is : {}", cells.length);
