I have a question regarding the actual availability of the trains ingame.
I have a bunch of trainsets, including Japanese Set:3. When I tried to auto-replace one of the trains, from another set, to a new model from this set displayed on the list of available trains, the task won't end and the train will run as it normally would without being replaced, despite having entered depots several times.
I thought it could be a compatibility problem between sets, so I decided to manually replace it, but when I try to find the train I want, it won't be listed on the "new rail vehicles" list.
Here's a picture that describes this problem better.

To the left, the trains for replacing, with an EF81 available; to the right, the actual available trains for purchasing. As you can see, none of the EF series is showing up on the latter, so I can't buy the EF81.
Am I doing something wrong?, or is this a NewGRF problem?
Thanks in advance.
