Detections for Rules using window keyword have duplicate period values

[stroomdev10]

I have a Rule that uses window, when it fires the generated Detection has two instances of period0 and period1

    <value name="period0">101</value>
    <value name="period1">22</value>
    <value name="period1">22</value>
    <value name="period0">101</value>
