What is wrong with the Jem'Hadar Attack Ship model/shield textures?

I've been noticing that the Jem'Hadar Attack Ship has been switching at least twice between two different models or series of texture templates which affect certain shield visuals (especially the counter-command covariant one).

While the problem may be older, I have screenshots showing it to happen in June 2014 and until now. Note that the screenshots don't indicate when the changes happen. You can achieve this by equipping the counter-command covariant shield from the 8472 reputation system:

"First" version (June 2014).
"Second" one (October 2014) Note how the 2nd pair of rings is now fully visible for a better effect.
Same with a better-lit environment (mid-November 2014).
Back to the old version (end of November 2014) covering the rings.

If you look closer, you can also notice the current version has the side parts of the ship nose having the rings being lower compared to the previous version (note how the mid-November version has the windows nearly touching them, allowing the rings to be higher than the 2 rectangles).

Could a dev tell us what is exactly going on and when will it stop?
