I checked your project and for me it’s OK. I found only one issue. In the udp channel for OSC, there was no value for Router Hops. This value should be at least 1.
You are using Port 7001, the default port of the OSC monitor is 7000 for receiving (see my screenshot). Did you change the default port for receiving to 7001? if so, did you also change the Echo port to something else? Because the default for Echo is 7001. If not, this can result in a conflict.
Anyhow, if I send 1.0 the OSC monitor receives 1.0
