TAG KEYS not working properly

I have 3 influx machines with me.
Two in Linux1, Linux2
and other in Mac

Step 1
Created a new_measurement for an existing database for both machine using insert operation,
–> insert new_msr,tag1=tagOne,tag2=tagTwo field1=‘fieldOne’ field2=‘fieldTwo’

Step 2
After that select statement in both, showed the record correctly in all machines

Step 3
Show field keys from existing_db shows, field1 and field2 as fields correctly in all machines

Step 4
Show tag keys from existing_db showed,
–> tag1 and tag2 in 2 machines Linux1 and mac
–> Empty (showed nothing) in Linux2

What might be the problem in Linux2 machine??

NOTE: All the influxdb.conf is same
