Erg Mode Power Spikes

Often when I am doing a workout on ERG mode (with a Wahoo Kickr V5) when I stop pedaling for a short amount of time or pause the workout ERG mode will switch off. The issue I am having is when I try to switch ERG mode back on, almost every time my power will spike to 2000w for 1 second then return to normal. This is very frustrating because not only does it stuff up the power chart for the ride, but Zwift now thinks my max power is 2000w when realistically its 950w (18w/kg). I have had this issue for a long time and I would like to know if it is an issue I can fix or if it is a problem with the game.
