Why do I get firearms warning?

[microvolk]

I am trying to list an antique engineers vernier /depth gauge. Made in France with imperial & metric measures. Each time I hit list item up comes the firearms warning. I can't get past it despite identical words on similar live listings. Can't even click an "understand" button & continue as it doesn't apply. What is going on & how can I get past this stupid block.

I can't find a way to remove any potential words that the bots are recognising without losing the pertinent description of the item. 

Thank you

Check which catergory the others are listed in, click on a listing and it is in blue at top of listing.
Stupid american robot probably thinks you are try to sell a cannon/mortar sight.
If you are using a mobile device this may be the problem and you will need to try from a desktop.

OK I just got it again with a Moore & Wright Depth Gauge! same category. I think the bots think I am selling depth charges!
