[TYPO3-shop] upgrade tt_products 2.4.8 to 2.7.4 missing category mode

[Man Math]

Dear All,

I am working on upgrade extension of tt_products from 2.4.8 to 2.7.4 
with TYPO3 4.5.22.

After upgrade, I could found some critical error with display products 
on front end.

Plugin shop does not show field for select Category mode (missing one 
field in flexform), otherwise, I could see for version 2.4.8.

Any suggestion or idea to solve this?

Thanks,
Man
