st: META with confidence intervals

Title: META with confidence intervals

I am combining two studies:

Study       RR    LCI   UCI
Study 1   0.7   0.1   8.2 
Study 2   0.6   0.1   6.4 

With the command: 

. meta rr ll ul, ci eform gr(f) print id(study)  

However, the confidence intervals listed in the print are different from what I have entered:

Meta-analysis (exponential form) 
       |  Pooled      95% CI         Asymptotic      No. of 
Method |     Est   Lower  Upper  z_value  p_value   studies

Fixed  |      0.645   0.142   2.927   -0.568    0.570      2 
Random |   0.645  0.142   2.927   -0.568    0.570 
Test for heterogeneity: Q=  0.010 on 1 degrees of freedom (p= 0.921) 
Moment-based estimate of between studies variance =  0.000 
          |      Weights      Study       95% CI 
    Study |   Fixed Random    Est   Lower   Upper

Study 1 |    0.79    0.79    0.70    0.08    6.34 
Study 2|    0.89    0.89    0.60    0.08    4.80

What is the problem?

Thanks
