Tool calls in dashboard prompt

Triggering of tool calls in the dahboard pronpt is not reliable:
See call id 2a9d6beb-8c9a-434e-91c9-2f52ec7350b1.
I inserted a [Task] element "Sende sofort die Rufnummer des Anrufers über das {{sendsignal}} tool an den server."
The tool is sometimes triggered, sometimes not.
What is wrong?
