Ikea Symfonisk Push Button & Call Scene

Howdy,
I have an issue which I assume is a bug with phoscon.

I am unable to set the push button on my ikea symfonisk to any Call scene option.
When I do, I am able to select options and click the save button, but then I get sent to the Available switches page. Toggle On/Off works though…

The call scene option works fine with my ikea tradfri shortcut button.

Otherwise, the symfonisk works perfect as a dimmer.

Platform: Raspberry Pi 3B+
Phoscon: 2.13.01 / 2021-10-06
ConBee II Firmware: 26720700
USB Extension Cable: Yes

So I figured out a workaround for the time being…

Setup the symfonisk and assign the push button to a single function like Turn Off.
Then using a REST client, change the rule to be a next scene function.

GET /api/<apikey>/rules

Find, and note, the turn off rule with the symfonisk, looking for its mac address makes it easier.

Copy the rule of interest, for example rule id 15 here:

"15" {
"actions": [{
  "address": "/groups/5/action",
  "body": {
	"on": false
  },
  "method": "PUT"
}],
"conditions": [{
  "address": "/sensors/65:4e:5f:c5:80:a2:f2:1c-01-1000/state/buttonevent",
  "operator": "eq",
  "value": "1002"
}, {
  "address": "/sensors/53:03:a3:69:5e:36:5d:18-01-1000/state/lastupdated",
  "operator": "dx"
}],
"created": "2021-10-26T13:57:43",
"etag": "89we07rf0w98fsdnofiusdoifuho9387",
"lasttriggered": "2021-10-26T14:23:20",
"name": "Rule OFF",
"owner": "J8ASKA9A7H",
"periodic": 0,
"status": "enabled",
"timestriggered": 25
}

Modify it to become like this:

{
"actions": [{
  "address": "/groups/5/scenes/next/recall",
  "body": {},
  "method": "PUT"
}],
"conditions": [{
  "address": "/sensors/65:4e:5f:c5:80:a2:f2:1c-01-1000/state/buttonevent",
  "operator": "eq",
  "value": "1002"
}, {
  "address": "/sensors/53:03:a3:69:5e:36:5d:18-01-1000/state/lastupdated",
  "operator": "dx"
}],
"created": "2021-10-26T13:57:43",
"etag": "89we07rf0w98fsdnofiusdoifuho9387",
"lasttriggered": "2021-10-26T14:23:20",
"name": "Rule CALL_NEXT_SCENE",
"owner": "J8ASKA9A7H",
"periodic": 0,
"status": "enabled",
"timestriggered": 25
}

Then put the modifications into place using:

PUT /api/<apikey>/rules/<id>/

Symfonisk button now works as a scene changer, still shows up as Turn Off in Phoscon.
Some specifics have been randomized.
