recordIdentifier weird behaviour while using in Post Feed Smart Service

Hi,
I have found a weird behavior while using recordIdentifier in Post Feed Smart Service, I need to display recordIdentifier for feed, the record is having title and no security has been set to record yet. When we mention recordType and identifier value without key, it works for 2 to 3 time execution, but after that again it starts to post feed without recordIdentifier, the configuration is shown below:

a!toRecordIdentifier(
cons!MYRECORD_DEMO,
1
)

Again when we mentioned the recordIdentifier function as key and value pair, again it works for Several execution, and again it starts to post the feed without recordIdentifier, the configuration is shown below:

a!toRecordIdentifier(
recordType: cons!MYRECORD_DEMO,
identifier: 1
)

Please suggest me, did anyone face the same issue, any suggestions will be appreciated

Thanks
