Hi on this panel there is 2 capacitors on the input but not ln the output could they be shorting voltage back to ic drivers when the dasiy chain being used

I was thinking when pinballsp said about inpendance issues would removing 2 caps and unsolidering the cure the.bleeding issue ?

As i was looking and wondered why less capacitors may be for smoothing voltage or are they charging and discharging
