Fix: Calculator values not saving / resetting
What you’ll learn
How to fix the most common reasons Calculator inputs don’t stick (reset back, revert after refresh, or don’t sync), plus what to include when reporting the issue.
What this issue looks like
You might notice one of these:
You enter values, but after leaving the page they go back to the old numbers.
You refresh and the Calculator resets.
Net Profit changes in the Calculator, but later the numbers revert.
You type a value and it “jumps” back immediately.
Fix it fast (do these in order)
1) Make one change and confirm it “sticks”
Open the product’s Calculator card
Change a single field (example: add +1 to a cost)
Wait a moment (or click Save if there is a Save action)
Refresh once
If the number remains after refresh, saving is working.
2) Avoid multiple tabs (this causes silent overwrites)
If you have D2C Lab open in multiple tabs, one tab can overwrite the other.
Fix:
Close all D2C Lab tabs
Open one fresh tab
Try saving again
3) Try incognito/private window (tests cache/session issues)
If it works in incognito but not in your normal browser, it’s almost always:
cached session data, cookies, or an extension interfering.
Fix:
Clear site data/cookies for
d2clab.coDisable ad blockers/extensions for the site
Log in again
4) Hard refresh
Windows: Ctrl + Shift + R
Mac: Cmd + Shift + R
Then re-test saving.
5) Test a different browser
Quick test:
Chrome ↔ Safari ↔ Edge
If it works in one browser but not another, it’s likely a browser-specific caching or extension issue.
6) Check you’re editing the correct product
This sounds obvious, but it’s common when working fast.
Best practice:
Go to Master List
Click the product’s Net Profit
This opens the exact Calculator card for that product
Common causes (what’s usually happening)
Cause A: Autosave didn’t complete (network / session)
If the connection drops briefly, your changes might not persist.
Fix:
re-enter the value
wait a moment
refresh once to confirm it persisted
Cause B: Another tab overwrote your values
If two tabs are open, the last one to update can overwrite.
Fix:
use one tab only
Cause C: Browser cache or extension interference
Some extensions block scripts, storage, or API calls.
Fix:
incognito test
disable extensions
clear site data
Cause D: Rapid editing / navigation
If you change many fields and immediately navigate away, the last change may not persist.
Fix:
after making changes, pause briefly
then refresh once to confirm
Quick checklist (30 seconds)
✅ Close extra D2C Lab tabs
✅ Make one change → refresh → confirm it stayed
✅ Try incognito/private window
✅ Hard refresh
✅ Try a different browser
