I'm trying to make uCurrent, it is a good project for hobbyist.
https://www.eevblog.com/projects/ucurrent/https://www.eevblog.com/files/uCurrentRev5schematic.pdfI have created in KiCAD, just copied Dave's schematic. And created my own PCB layout. I have used 0.1% resistors (instead of 0.05%).
Problem is I see oscillations across R8, which is at the output of second opamp (see attached oscilloscope screenshot).
I'm feeding 10mA DC to the input jacks, and expecting 10mV at the output jacks. Output of the first opamp gives 1mV (which is as expected). But output of the second opamp gives wrong values (negative millivolts - that is probably caused by those oscillations)

I tried to change opamps, just to verify whether one of them is faulty. Didn't help.
I tried to change capacitors, even tried to change values of C3 and C4 to 5pF or 30pF. Didn't help.
What could be wrong?
