InfluxDB batch insert only inserts the last line

I'm trying to insert some lines into a InfluxDB instance (running on Windows 7 x64) from both a .txt and a .csv file, but it's only inserting the last line on the file. I'm currently using the Insomnia interface to send the file through Influx's HTTP API. Example: I have the following content inside a data.txt file: any,mytag=ab value=59 any,mytag=ab value=78 any,mytag=ab value=102 All lines are ending with LF only (verifying it through N++). Then I send this file via an HTTP request to my running InfluxDB instance:

POST http://localhost:8086/write?db=mydb&precision=ns

Yet, when I do a select * from "any" query, it shows that only the last line (value=102) was inserted. I've also tried inserting through text/plain content but to no success as well. Any idea on this? Thanks.
