ids setting not show in backend

Hye, again
In all block where you can set id’s for category product or product

Exemple Term (Category) blocks) :
you set
Taxonomy : products category
…
Include Terms : 3 or 4 ids …
Save.
All work well back and front.
Come back on the page (allways view ok)
but : in Include Terms you have nothing, the ids are not printed.
(always works with the ids set before, if you did’nt click on the field, but you can’t view the list in the field Include Terms)

Have a nice day
