mmcli dump list key value issue

There seems a small issue in "mmcli -m 0 --messaging-list-sms -K" reporting (in MM 1.18.6). When the number of SMS is >= 100 then closing square bracket for the message index is missing in the output as shown below (see index 100 and above, closing square bracket is missing). Please advise how this can be addressed.

This is an example and similar problem will be with other key/value pair with >= 100 entries

mmcli -m 0 --messaging-list-sms -K modem.messaging.sms.length : 189
