Sorry but screenshots are of no use to make a case. You'd need to send code.
However I see that you are using for example filtfilt in python which is an a-causal filter running in neg and positive time to achieve linear phase on an array while iirj is a causal filter. See also discussions about this on the sister iir1 c++ filter. This crops up at regular intervals and is the result of atrocious DSP teaching with MATLAB heritage and sadly also misleading comments all over the web. For a starter you you'd need to use lfilter in python which is the real causal filter. However, I'm sorry I cannot teach you digital signal processing here but you'll find my youTube videos here: https://www.youtube.com/dspcourse.
