Condition of using Create Maestro Plotting Template

Hi all,

For these two blogs, 

[1] https://community.cadence.com/cadence_blogs_8/b/cic/posts/virtuoso-ic6-1-8-viva-plotting-templates

[2] https://support.cadence.com/apex/ArticleAttachmentPortal?id=a1O0V000009ETFiUAO&pageName=ArticleContent&sq=

We can see the create templete function, is select File -> Create Maestro Plotting Template

But on my system, the selection is grey. I tried the two situation, 

1) The Viva XL started by ADE Explorer, while the simulation complete, I have some plot output.

2) Manually plot from results tab.

The Viva XL opened in both way disabled the Create Maestro Plotting Template.

My software version:

$ virtuoso -V
@(#)$CDS: virtuoso version IC23.1-64b 06/21/2023 09:33 (cpgbld16) $

$ spectre -V
@(#)$CDS: spectre version 21.1.0 64bit 05/22/2023 19:47 (mmsimcm36c-4) $

What settting prevent me from the Create Maestro Plotting Template?

Thank you in advance.

Best,

Simba
