Using ELP mapping configuration changing after PUT submitting

I use Postman, using Put to specify the hops of ELP, and I condigured them as strict:¨true¨: as shown below, but after that I use GET to check, I found this strict becomes ¨false¨.

{
"key" : "asdf",
"mapregister" :
{
"proxyMapReply" : true,
"eidToLocatorRecords" :
[
{
"authoritative" : true,
"prefixGeneric" :

{ "ipAddress" : "2.2.2.2", "afi" : 1 }

,
"mapVersion" : 0,
"maskLength" : 32,
"action" : "NoAction",
"locators" :
[
{
"multicastPriority" : 1,
"locatorGeneric" :

{ "ipAddress" : "10.33.12.37", "afi" : 1 }

,
"routed" : true,
"multicastWeight" : 0,
"rlocProbed" : false,
"localLocator" : false,
"priority" : 124,
"weight" : 1
},
{
"multicastPriority" : 1,
"locatorGeneric" :
{
"afi" : 16387,
"lcafType" : 10,
"hops" :
[
{
"lookup" : false,

},
{
"lookup" : false,
"RLOCProbe" : false,
"strict" : true,
"address" :

{ "ipAddress" : "10.33.12.37", "afi" : 1 }

}
]
},
"routed" : true,
"multicastWeight" : 0,
"rlocProbed" : false,
"localLocator" : false,
"priority" : 125,
"weight" : 1
}
],
