This thread is resolved. Here is a description of the problem and solution.
Problem: translated the a number of products (about 30) and then I translated the main start page. Then I went into WPML settings and saw a notice about that there was new translated content created and something about "do you want to scan strings to configure and change all the connections and links?" I said yes and now it is "Scanning strings.. 510 of 22590 done..."
Is this normal?
Solution:This is normal. This means when you create new products some new fields are created. These might be attributes, variations, etc.. As long as you do not see any translations issue by not scanning all the strings is NOT an issue because 22590 is not just from the products. WPML indicates all the string are from themes, plugins, products and more..
If you want to scan them all for translation you can go to WPML > Theme and Plugin localizations and scan them selectively or all but it's better if you do not do this until you really needs it because this will increase the size of your database and you site may get bit slower as the system will get many strings to scan and process every-time.
So no worries for now!
