Multisite works but brings sometimes different deploy IDs sometimes not

1) I installed WP enabling multisite

2) Installed the plugin via network admin and it works well on the first site.

3) Then, I can’t remember the order of things, but I created another site and yes, the slideshow “tab” in the site specific section was there but you had to add another slideshow to the site, otherwise nothing shows (that is, one thing is that the Menu Label Slideshow shows, other thing is that you actually need to add it . So you add one and the deploy id that comes is different from the first one of the site 1. Since I only have one WP installation when I go to editor, I either have to leave untouched the former id deploy number, in which case the first website would work, or change it to the second id, in which case site 1 would not show slideshow but site 2 would. Curiously, if I create site 3, site 4 etc all of them do the right thing in that they always provide the same deploy id (number 4 by the way), so that all of them will show the slide without having to enter any deploy id at the editor. However, the first website still wants his first id, which was 15. If I create another slide show inside the first site it will give 16, another one in the first site 17 and so on. If I create another slideshow in site 2, it will bring deploy id 5, (so the next in successive order). If I create a new site 5, the deploy id will provide a good number 4 again.

No way to solve that. So I disabled the plugin and deleted and re-installed it. Same story, if you create a slideshow in the first website, it will be number 16, if you create it again in site 2 (which already exists) will bring deploy id 6 (its successive number). Only when I create a completely different site, say site number 3434, then when adding a new slideshow, it brings again the steady deploy id 4.

The problem is that my first site is finished, all the content is there. I dont know how to copy all the content to a new website (which would bring deploy id 4).
