P800 VM (WT-DG) cartridge leaking

Hi
My VM cartridge (WT-DG) seems to be leaking… After refilling for a first time 2 weeks ago I noticed it is again empty whereas all other cartridges are at about 60%.
I have an extra cartridge but lost quite a lot of ink!
Has anyone else had this problem? There mut be enough ink in the lines as I printed nozzle checks a few times and a few prints and had no problems…
Attached are photos of the cartridge and ink cavity on the p800.

These carts can leak if the film between the ink and pressure areas is damaged (most often in shipping). Please PM your ink loss quantity.

best,
Walker
