floating sign doesn't appear on polybar

Describe the bug

When i activate the function "togglefloating"(default binding mod+shift+space), the polybar dwm module doesn't appear the "F" sign, which it suppose to.

However if i launch polybar in command line(after dwm launched), the floating sign will only appear on the tag where the terminal is, but if i jump to other tags the sign won't appear again.

Expected behavior:

polybar dwm module should appear a "F" sign when togglefloating at anytime.

Actual behavior:

The sign doesn't appear when togglefloating.

Was it working before?

• Did you also experience this bug in an earlier version of polybar ? (i don't know(
• If no, what was the last version where this worked correctly?

To Reproduce

try to toggle floating

my polybar config
