cc @merrymercy @jcf94 please look into it and send a fix

I guess it is introduced by #6529.
You can revert #6529 if the issue is urgent.
I would like to assign this task to @jcf94

Thanks. I will check this carefully and fix it as soon as possible.

Looks like the same problem as #6557 fixed. Should be fine now.
