Two-way-ANOVA in


I am using for a two-way-ANOVA with repeated measures on both factors. The results for row and column variables seems to be alright, but the interaction effect between row and column variables shows a F value of 0 and a p-value of 1. I don't understand how I should interpret such a result. Can anyone explain to me what a F value of 0 indicates? I have attached a photo of the results from the analysis. Thank you in advance.
