Automatics parameters such map_tec_time presenting weird behaviour

Dear

Let me try to explain this issue properly.

I have 4 sub time periods: [SUMMER, SPRING, WINTER, FALL]
and a parent time which is YEAR

I have a technology X that works on the sub-annual time, the seasons however, if I set a relation XR associated to this technology X when IXMP generates the gdx file it creates a map_tec_time and map_tec_act sets automatically but with time year also associated to the technology X.

Therefore, instead of get the result as I was expecting, such as:
X, node, year time=[SUMMER, SPRING, WINTER, FALL]
I got
X, node, year time=[SUMMER, SPRING, WINTER, FALL, **YEAR**]

If I try to pass those sets to the model manually I get the following error message:
`com.gams.api.GAMSException: Symbol map_tec_time exists already`

How can I deal with this issue?

All the Best and thanks in advance.

Start at the IXMP generation of map_tec_time and map_tec_act and reproduce the seasonal/year case described in the issue. Check how the automatically generated symbols interact with manually supplied symbols; done means the behavior and the duplicate-symbol error have a documented resolution.
