Module VirtueMart Products get lost

[virtuenewbee]

Hi,
This happens second time:
1. I check my shop and I see the Module VirtueMart Products, is lost
2. I go to the module, where I have Module Class Suffix defined as, say, toptensfx
3. I change that to, say, toptensfxyy, save, refresh and I see my module is shown back
4. to get my css design back, I again change the altered one (toptensfxyy) to the original (toptensfx)
5. finish: all is back again!

I know this is not a repeatable error as I can't say what causes this but do you have any idea, why the module gets lost by reading steps? I think it must be related to the Module Class Suffix.

Any idea please?

I observed new behavior:

Sometimes I open the shop and I see only 5 items in top-10, even though I have 10 products marked as featured in the products list.

Solution is the same:
I go to the module
Alter the name of Module Class Suffix,
Save
Change back to the original suffix
Save
Refresh front and they are back!

Even if I suppose that the template style is not fully load, then how that is that 5 of the items are shown there and others, not !!
