Custom projects error

Example: Let us suppose that there is a custom project named "EURUSD_H1" and I create its clone. The clone is automaticelly named as "EURUSD_H1(2)" by SQ. Thus, there are two custom projects: "EURUSD_H1" and "EURUSD_H1(2)". That is OK. I change the name of the clone to "EURUSD_H4" and I change settings of the projects (for example, the time frame or some other settings). Thus, there are two custom projects: "EURUSD_H1" and "EURUSD_H4". That is OK. However, after the next start of SQ, there are three custom projects: "EURUSD_H1", "EURUSD_H4" and "EURUSD_H1(2)". It is necessary to manually delete the redundant project "EURUSD_H1(2)".
