how do I connect a province to the sea?

[MonterosJose 0]

I have the problem that the mod that I downloaded (and that happens in the original game) is that some provinces attached to the sea can not go by sea, and I was looking and the other provinces are at 0, while those that do not work are at -1.

Here the examples:

and sincerely I am years trying to fix it, but I never knew how, could you help me how to connect? (and if you tell me to connect as if it were normal, it does not work, as you saw in the image they have special lines, if I connect as if it were a province, it appears with lines).

here the example:

Thanks you

Well I don't know if it will work but, first remove the connections with the seas and lakes from the terrestrial province, then set the terrestrial province to -1, after that connect the seas and lakes to the province and according to what I tried with my map and from what i remember, it should be set to 1 and you could build ports

I'm not sure if this will work, but you should disconnect the terrestrial province from the seas and lakes, then set the terrestrial province to -1, and finally reconnect the seas and lakes to the province. The terrestrial province should then be set to 1, allowing you to build ports, based on what I remember from playing with my map. Now it's time to avail this scholarship essay writing service for more details. Best wishes.

For me, this represents the next step, so I appreciate the advice. However, I'm currently facing some challenges with writing. I recently encountered this issue and found a suitable solution for myself. Thanks to dissertation writer for hire, I was able to deliver high-quality work to both my teacher and classmates.
