Companies House are providing present IDs with an "E" as a leading character.

This is not accepted when using the TaxCalc application.

Updating to the Summer release will resolve this.

In some cases the Nominal Ledger report will display duplicate director-allocated postings when a director is also the company secretary

- un-allocate the directors from the postings, though this will show as un-allocated in the nominal ledger, or

- Temporarily delete the Company Secretary relationship when reviewing the Nominal Ledger.
