Cannot save an assembly after changing a parameter

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

It is preferred that models are stored in default orientation and occasionally I find that I cannot save because I the only change I have done since the last save is change the view on the screen. I will then either do a quick reorder (and back) or create a datum and delete it.

There is always more to learn.

I have found that changing a parameter value does not flag Creo to think the file has been modified and the file will not save with the message that file has not been changed. I then force another change, either a carriage return in the relations or delete an unnecessary parameter that we don't use. This will then 'force' the system to accept the change and do the save.
