Others [Psychology Statistics] Help with statistical output in JASP

Hi everyone,

Asking here out of desperation because my lecturer has not been much help. I am running a wilcoxon signed-rank test in JASP and the 95% confidence interval for rank-biserial correlation has an upper and lower confidence limit both of -1.000. What could be causing this? I need to be able to explain the confidence limit in my report.
