WSIB Payable account

I cannot figure out why there is constantly a surplus in my payable account for WSIB.  I had to do an adjustment of 301.46 last month and now 152.83.  I have checked all of my employee accounts individually and the percentage is correct.  Here is an example of my own calculation Employee #1 Gross Wages are 1,707.48 My rate is 2.98% according to my calculation 50.88 should be put into the payable account but it actually reads 76.84.  Please let me know if there is an explanation for this.. I have included the entry below as it looks in Sage.  I am new to this so hopefully someone can let me know what I am doing wrong.
