You are trying to upsert values in your SF instance using OData in some entities (example EmPayComponentRecurring) that stores values like salary, bonus and you are passing the value like 1122.11.
After your OData API upsert, checking your user interface, the value stored is 112211 and not 1122.11.

The default value is English and probably you are using another language. That's why the upsert get confused about the dot / comma and generates issues in decimal numbers
To solve this issue, please change the API username language in the SF settings (top right Options > "Change Language" > change for English US).
