nist msms

I have a question about the library Nist msms, when i do "Export to library browser" to analyze the peak by m/z, this parametre is changed automatically, no decimal is affiched and the value is increased ( for example, as mentionned attched, 890.64 that is changed to 891 ). Even if the compound is disponible at the data base, of negatif mode.
I would like to know how can i conserve the same m/z affiched in Xcalibure.

thank you
