There is something that have messing with me the last days and I cannot find something similar so far.
The issue is, I have already over 1000 products for certain model, in this case STK-XXXX.
if I filter all products that start with "STK-" the result will only show me until STK-999 and that's it, product STK-1000 will not appear unless I do a specific filter for that product number, otherwise it will be like hidden.
I also match the display order with the product number, just in case this information is useful to an expert.

I once thought that it was something to do with the settings of my php, but I have everything correct.
I also have changed the display order but the result is always the same.
I hope someone can help me
