I'm trying to monitor some SNMP items using Template level macros combined with item level values. When server replaces macros, some values appear in the generated oid string that are not referrence anywere.

Example:
Template Macros: {$BASE_OID} -> .1.3.6.1.4.1.11.2.29.2.5.3, {$REAUTHREQ} -> 1.6.0
Item definition: SNMP OID -> {$BASE_OID}.2.{$AUTHREQ} (does not works ok)

Item resulted string should be: .1.3.6.1.4.1.11.2.29.2.5.3.2.1.6.0, actual string: .1.3.6.1.4.1.11.2.29.2.5.3.10.2.1.6.0

Log:
