Is there any chance the label pictogram is actually 10x10mm?
Guidance on Labelling and Packaging Version 2.0 - September 2016 states in section 5.2 (Size of the label and of the label elements) that for a package of capacity less than or equal to 3 litres, the pictogram (in this case the flammable hazard pictogram) must be not smaller than 10x10mm and if possible at least 16x16mm.
It's likely that while the printed pictogram is not that much smaller than the label, that difference was enough to not quite meet regulations.
There's also another other regulation that can come into play: "Each hazard pictogram must cover at least one fifteenth of the minimum surface area of the label dedicated to obligatory labelling information."
These are EU guidelines, so it also depends where you are.
Note: the linked document is only a guidance document produced by the European Chemicals Agency and the actual legally binding document, known as the 'CLP' is the 'Regulation (EC) No 1272/2008 on Classification,
Labelling and Packaging of Substances and
Mixtures'. Having said that, the UK Health and Safety Executive (HSE) still officially references the linked ECHA document 'for more information'.
