I wrote while setup

and see it in Winbox now, but export show-sensitive shows

/routing filter rule
add chain=bgp_in disabled=no rule="set gw *13; accept"
what is this? why “*13”, not “vpn”?
is the internal interface ID
Thank you, yes, this is internal id of interface, but question is why it translate name to id in export? How to restrict this manner?
I using export for backup in case of hardware lost, but with this translations I can’t apply script to another router and can’t understand it 
It’s a bug, open a support ticket. I have just tested it, and not only that the export shows the internal interface id, but it even shows a wrong one. Try /interface/print where .id=*13 - in my case, it looks as follows:
_[me@chr-7-1] > routing/filter/rule/print
Flags: X - disabled, I - inactive
0 chain=test rule=“set gw huhu ; accept”
1 chain=test rule=“set gw eoip1 ; accept”
[me@chr-7-1] > routing/filter/rule/export
/routing filter rule
add chain=test disabled=no rule=“set gw *13 ; accept”
add chain=test disabled=no rule=“set gw *9 ; accept”
[me@chr-7-1] > interface/print where .id=*13
Flags: R - RUNNING; S - SLAVE
Columns: NAME, TYPE, ACTUAL-MTU, MAC-ADDRESS
18 RS vxlan1 vxlan 1300 76:B2:F6:54:DC:DC
[me@chr-7-1] > interface/print where .id=*9

I think is already solved, please wait new 7.3
