completionTime weirdness?

I am using Home Assistant and the completion time for my washer/dryer is always some phantom date.

For example: my washing machine is running, completion time is 12:34 (time zone +1)

"washerOperatingState": {
"completionTime": {
  "value": "2026-01-31T11:34:22Z",
  "timestamp": "2026-01-31T11:05:22.062Z"
},
"machineState": {
  "value": "run",
  "timestamp": "2026-01-31T09:50:28.743Z"
},
"washerJobState": {
  "value": "spin",
  "timestamp": "2026-01-31T11:16:43.342Z"
},
"supportedMachineStates": {
  "value": [
	"stop",
	"run",
	"pause"
  ],
  "timestamp": "2026-01-31T07:26:19.618Z"
}
},

After completion of the washing machine this is the status I get:

"washerOperatingState": {
"completionTime": {
  "value": "2026-01-31T14:12:40Z",
  "timestamp": "2026-01-31T11:34:40.921Z"
},
"machineState": {
  "value": "stop",
  "timestamp": "2026-01-31T11:34:40.921Z"
},
"washerJobState": {
  "value": "none",
  "timestamp": "2026-01-31T11:34:40.921Z"
},
"supportedMachineStates": {
  "value": [
	"stop",
	"run",
	"pause"
  ],
  "timestamp": "2026-01-31T07:26:19.618Z"
}
},

Now it throws some time in the future, the washing machine is clearly not running anymore (machineState is stop, washerJobState is none).

What is going on, why do I get a date returned in the future.
