Cannot save an assembly after changing a parameter

[Hidetaka]

I ran into a large assembly that I cannot save after changing some parameters.
The parameter does not seem to have anything to do with regenerating the assembly (it is date and designer name).
From the warning messages that appear after I tried to save the model, I have found 2 support articles, but I could not read them. Could someone please tell me what is in these two articles? Thank you so much!

The first (CS258240) indicates it is a result of regeneration failing. The "Resolution" in this case is:

• Reported to R&D as SPR 6497841
• Works to product specification for Creo Parametric
• Creo Parametric returns to old/unexpected values, when regeneration is not completed and not sure if new value is suitable or not.

The second (CS112336) seems to relate to "Model is not regenerated" and "Mass properties are not calculated" errors. Its "Resolution" is

• Reported to R&D as SPR 5152497
• To disable model regeneration and mass calculation when saving model
    Set config.pro options mass_property_calculate to by_request and regen_solid_before_save to no
• ​To enable model regeneration and mass calculation when saving model
    Set config.pro options mass_property_calculate to automatic and regen_solid_before_save to yes​

Disclaimer:
PTC recommends to backup the config.pro file before modifying it
