Hello,
I can see the issue in your block JSON file and reproduce it on my demo site
"icon": "admin-page",
"id": "productshow",
"include": {
"ID": [
1082
]
},
"modified": 1766028032,
"supports": {
"anchor": true
},
"title": "productshow",
"type": "block"
you can see that the block will be displayed (include) on the post ID 1082, which isn't correct. To fix the issue, you can select the Rule: Post type, remove all Advanced rules, then select Rule: Block again.
Let me know how it goes.
