1. When using a beta prior with mean 0.2 and variance 0.5 as in the attached mod-file Dynare warns that the prior has two modes. Nevertheless it continues but then is unable to compute the prior distribution (everything is NaN). Shouldnt we abort with an error message in this case?
2. The preprocessor warns that Prior distribution for parameter e_R,e_g has two modes! Would it be possible to add corr before e_R,e_g?

It is indeed necessary that (1-mu)*mu > sigma^2 otherwise the natural parameters of the beta are negative and the density doesn't exist. I added the necessary test.
2.The preprocessor warns that "Prior distribution for parameter e_R,e_g has two modes!" Would it be possible to add "corr" before "e_R,e_g"?
I made the correction
Best
