For your desired output, you need to drag the LTE_Payload_TB under the column Field and above the date column.
If it is convenient, could you share your sample data in text-tabular format in addition to (or instead of) screen captures. That allows people trying to help to readily copy the data and run a quick test, plus it increases the likelihood of your question being answered. Just use 'Copy table' in Power BI and paste it here. Or, ideally, share the pbix (beware of confidential data).
