example POLYMER-01 - WOPR decrese/increse

[EnriqueRamonV]

Hello,

I'm testing the visualization of example POLYMER-01 in ResInsight, and I wanted to know if someone can explain to me why when polymer injection starts (2kg/day), the WOPR decreases, and when polymer injection ends (0 kg/day ) , the WOPR increases instantly? (Attached image)

Thank you for the response.
