last year approved AP soft LUD question

I recently landed in Canada and used my AP reenter US. today I noticed there is a LUD on my long approved AP.

I am a little bit concerned about this AP LUD because the border officer gave me a hard time about landing in Canada while adjust status in US. He was questioning my intend.

Does anyone on this board have similar situation? I am a bit concerned because I do not know whether the border officer would have any impact on my pending 485 case.

Thanks
