There seem to be a couple of sign errors in the manuscript. (Probably worth reaching out to the authors directly)
Their predictive coding algorithm holds the vhat values fixed during convergence, which actually implies a somewhat different network topology than the more traditional one shown in your figure.
Thanks for sharing!

What are the sign errors?
Right side of equation 2. Also the v update step in algorithm 1 should have a negative sign (the text version earlier on the same page has it right).
vhat?
v hat = ^v.
