CSS is not working properly

Hello support, after copying the root website to subdomain we see both site are not identical.
When we deactivate asset cleanup plugin then both sites are showing identical.
We see main difference is like this type of file:
In root domain:
https://polarbd.com/wp-content/cache/asset-cleanup/css/item/sweetmielo__style-css-v0668357b9a63f9a57306486fa370f8482ad62.css
In subdomain:
https://staging.polarbd.com/wp-content/cache/asset-cleanup/css/head-558df182287ec1b1876585c9c4cfa035c30d8.css

I have copied all wp-contetn/cache/asset-cleanup/css from root domain to subdomain but no luck.
Any suggestion, how can we reset all stuff and make identical to root domain?

Thank!
