After xsd export to cif, why some bonds in cif disappear?

In the xsd,the crystal file has successfully connected the chemical bonds between the atoms. After exporting to the cif format, I found that some of the bonds information disappeared.

When I opened the source file of the cif file, I found that there is really no information about the missing bonds in the bonds list.Who has encountered this situation? Or who has a solution? The files are in the attachment, Thank you .
