SELECT request issue

Hi all,

i have a strange behavor with my InfluxDB time series (i use InfluxDB 1.7.4).

influx
> use mydb
> SELECT "value" FROM "foo" LIMIT 3
name: foo
time                      value
-----                       ------
1586678355         0
1586678356         1
1586678357         2
> SELECT "value" FROM "bar" LIMIT 3
name: bar
time                      value
-----                       ------
1586678355         STOP
1586678356         START
1586678357         STOP
> SELECT "value" FROM "foo","bar" LIMIT 3
name: foo
time                      value
-----                       ------
1586678355         0
1586678356         1
1586678357         2

In the last SELECT, bar value are not displayed…
Any idea ?

Note that it is work fine with another field (with value are all integers):

> SELECT "value2" FROM "foo" LIMIT 3
name: foo
time                      value
-----                       ------
1586678355         0
1586678356         1
1586678357         2
> SELECT "value2" FROM "bar" LIMIT 3
name: bar
time                      value
-----                       ------
1586678355         10
1586678356         11
1586678357         10
> SELECT "value2" FROM "foo","bar" LIMIT 3
name: foo
time                      value2
-----                       ------
1586678355         0
1586678356         1
1586678357         2

name: bar
time                      value2
-----                       ------
1586678355         10
1586678356         11
1586678357         10

Thanks !
