Hi!
I have conducted a CLPM and a RI-CLPM models in R using Lavaan. The models seem to work fine (goodness of fit indices, results) although I noticed that the unstandardized and standardized estimates look pretty similar (both in the CLPM and RI). I am using mean scales in the model (scaling 1-3), and to me, the data looks fine. 
I have pasted a copy of the results from the CLPM below. Basically, what I'm wondering is whether the similarity in the betas could be a sign of a problem or not?

Best regards, 
Kape

Standardized estimates are what you would get if the variables were z scores.  If your observed variances are close to 1, then you can expect standardized and unstandardized estimates to be similar.
