[Bug] Button panel not works as excepted when configured within a Grafana Row UI component

[clongnj]

Button panel not works as excepted when configured within a Grafana dashboard Row :

When the dashboard load at the first time, the button panel can not set the values from Row correctly, e.g.
there are 4 rows in the Row panel, then if I use $variableName in the button panel, then all the button panel will get the first value,
but if I manually refresh the dashboard by click :

Then each one of the button panels can set value to the $variableName correctly.
I reached out Grafana support and their said it is a bug of the plugin, please help to look into it.
Thanks!
