Creo 11.0.2: &PRO_MP_MASS[.2] Sometimes Fails to Format the Decimal Places

Hello everyone,

I have encountered an issue in Creo Parametric 11.0.2 that has been bothering me for many years. I hope someone can explain the reason or provide a reliable solution.

I want to display the model mass in a drawing title block or a regular note, rounded to two decimal places:

&PRO_MP_MASS[.2]

For example, if the actual mass is:

0.058

it should normally display:

0.06

However, sometimes it displays:

0.058[.2]

In other words, the value of PRO_MP_MASS is correctly retrieved, but [.2] is treated as plain text instead of being interpreted as a decimal formatting modifier.

What is even stranger is that if I edit the same note and temporarily change it to:

&PRO_MP_MASS

After confirming, I edit it again and change it back to exactly:

&PRO_MP_MASS[.2]

it may immediately display correctly as:

0.06

During this process, I do not modify the model, material, or mass properties. I only re-edit the note.

This issue can occur both in the title block and in regular drawing notes, so I suspect it may be related to parameter note parsing or refresh behavior.

Has anyone encountered a similar issue? Is this a known Creo problem? Is there a reliable automatic solution suitable for company drawing templates, without requiring users to manually re-edit the notes?
