Standardized regression coefficients

What causes this issue?

Standardization allows the regression coefficients to be compared
because standardization eliminates the influence that the different
value ranges for the variables have on the regression coefficients. The
standardized regression coefficient is calculated from the regression
coefficient aj as follows:
aj(standardized) = aj * Standard Deviation(xj) / Standard Deviation(x0)
