how to increase modules in WGCNA

Hi,

I did wgcna analysis to do the project I used 336 samples for this analysis, but in the end, it gave me 3 modules, about 16,000 genes, 12,000 in one module, 379 in one module, and 212 in another. I think I only have 3 modules and it is very unusual with these descriptions.

Based on the output below, I selected Power 10.

1- Is there a way for me to increase the number of modules?

2- I drew the following error to draw one of the diagrams.

3- Do you think it may depend on the number of modules?

4- And how to fix this error ?

Thanks.
