We have a custom text field that we created to store support reference numbers for issues. Our reference numbers use a mix of numbers, letters and hyphens, so we figured a text field would be best. We entered the references manually and they displayed fine, even after saving. But a week later I have noticed that the values we entered have been changed.
For example,
10383, 10860 changed to 1.050811523E9
11448 changed to 11448.0
9223, 9485 changed to 9.2239485E7
BUT
2022-12/RQ-MCC/0102 and similar references remain correct
How can we stop this happening? Do we need to use a different type of custom field?
