paired t-test shows no difference between median and Wilcoxon test p value shows that there is a difference between median values ? How to interpret?

I have a dataset. I wanted to do paired t test on it. So I carried out normality test and it showed that it does not follow normal distribution. So I used Wilcoxon test in place of paired t test. The descriptive statistics of my data shows median value of 0 but when I ran wilcoxon test, it gave me a p value <0.05 stating to reject null. Could you please tell me why this discrepancy in my test results?
